At a Glance: Our Top Picks of Air Purifiers for Hayfever

Best Air Purifier for Hayfever

This is because hayfever, also known as allergic rhinitis, is caused by allergies.

You will agree with me when I will say that we often overlook the need for breathing quality air in our homes.

We ignore the fact that where an increase in pollution makes it difficult to breathe quality air outside our homes, the air inside can be toxic as well.

According to research work conducted by the US Agency of Environmental Protection, indoor air can be two to five times more polluted than the outdoor air.


The high percentage of indoor pollution is due to the accumulation of dust, smoke, pollen, mold and chemicals in very confined space.

If the air quality is not improved, it becomes one of the sources causing hayfever.

At this point, it is quite clear to you how much air cleaning is necessary for your health. You have to find a way to deal with harmful microorganisms that can directly affect your respiratory system.

What to Consider When Buying the Best Air Purifier for Hayfever

Filtration System

The filtration system acts as the backbone of any air purifier.

It purifies polluted air by passing it through different stages of purification, where filters capture and eliminate the allergens and harmful contaminants.

In terms of air filtration, HEPA filters (generally known as the “True HEPA”) are currently the best in the world.

With its absorbent and fibrous material, it can capture the contaminants as small as 0.3 microns in diameter.

That increase its efficiency in capturing allergens of up to 99.97% making it the best filter one can install in the air purifier

In addition to HEPA filters, other filters commonly used in air purifiers are pre-filters, activated carbon filters, ionizer, UV Lights, and ozone generators.

The functioning of each of these filters is explained below:

  • Pre-filters generally capture large dust particles, and they help in prolonging the life of the main HEPA filter.
  • The activated carbon filter is added in the filtration system to remove the smell of smoke and cooking or any other odorous particles.
  • Ionizers, as the name suggests, charges small dust particles with a negative ion, which are then collected in a positively charged plate.
  • UV lights have the responsibility to kill bacteria and viruses. If the unit uses a type-c UV light, it is safest type in terms of harming humans.
  • Ozone generators often help in removing the mold and mildew, but if you are suffering from respiratory problems, there are chances that you feel irritation in your lungs. In this case, it is generally advised not to use these in your purifier unit.

If you are interested in learning more about the functioning of all the above-mentioned filters, you should spend some time reading this article.

Version of the Air Purifier

It is the second most crucial factor in selection criteria after the filtration system.

Generally, all of the air purifier units come with two versions:

  • Classic Version
  • Smart Version

When we say the term “Classic,” it means that they are not fully equipped with digital controls and air quality sensors, which makes them less accurate.

In these types of units, you won’t have idea about which and how much impurities can be removed by the air purifier.

On another side, “smart” air purifiers - as the name suggests, are those with sensors and mobile app accessibility like the Rabbit Air MinusA2 and BLUEAIR Classic 605 purifiers, which not only give you exact data of air quality but in most cases tells you about which pollutants are being removed by the purifier unit.

Using this data, you can easily estimate how well your air purifier is performing.

Coincidentally, all the units which made it on this list can be categorized as smart version purifiers.

ACH and CADR Ratings

Before selecting the air purifier, do check the ACH and CARD ratings as they play an essential role in the overall efficiency of the purifier unit.

These terms may sound technical, but they are quite simple to understand.

ACH stands for Air Changes per Hour, which means how many times the air purifier filters the polluted air present in a room with clean, fresh and contaminant-free air.

This rating is shown on devices as 4x, 5x, 6x etc.

Here, the purifier unit with ACH ratings of “4x” can replace the polluted air with fresh air four times in one hour.

The higher the number, the higher will be the efficiency of the air purifier unit.

CADR stands for a clean air delivery rate. This rating gives you an objective standard to see the effectiveness of your air purifier unit.

This rating is based on the capacity of the purifier unit to remove three types of air pollution:

  • Dust
  • Smoke
  • Pollen

If your device has a CADR rating of 190/210/170 – here 190 refers to dust, 210 to smoke and 170 to pollen.

The higher the numbers, the higher the effectiveness of the air purifier units in removing all these air pollutants.

Filter Replacement Indicators

Filter replacement indicators basically remind us to change our air purifiers filters.

These are pretty handy and one of our favorite features to look for.

If you run the purifier unit in a highly-contaminated place, the filters may become clogged faster than what is stated by the manufacturer.

In this case, they are beneficial in giving us an early heads up! 

Also removes the need to guesstimate when a replacement is needed.

Usually, there is a light on the unit which changes color when a filter replacement is needed.

Sometimes, there is a separate LED that starts glowing after the filter gets contaminated. 

If the filter is not timely replaced, it can decrease the efficiency of the unit to a great extent.

So, you should pay great attention and regularly check the health of filters. 

Room Size

Even with advancements in technology, there are still certain limitations in the functionality of any human-made machine.

The same is the case with air purifiers.

Every purifier is limited in terms of space it can cover. The fan model and speed play an essential role in increasing its coverage capacity.

Generally, the manufacturer of the unit mentions the upper limit of an area that it can cover in the description of the product.

For large-sized rooms, an air purifier with an ionizer is preferred to disperse the ions throughout the space for better removal of contaminants. 

Other Factors

  • Programmable Timer: This feature shuts-off the purifier unit automatically after a specific interval of time programmed by the user. This saves energy, thus reduces the overall bills.
  • Multiple Fan Speeds: Make sure the unit you select can run at more than one fan speeds so you can adjust it depending on how quickly you want your purifier unit to exchange and clean the air.
  • Noise Level: Fan in the air purifier sucks air and then pass it through the filter for filtration. The higher the fan speed, the more noise it will produce. You should check the level of noise from the product manual before buying the product.
  • Pre-Filter: You may have read about this type of filter earlier in this article, and you should make sure the air purifier unit you are going to buy has this filter. Not all air purifier units have this filter.
  • Frequency of Filter Replacement: Every filter has a specific life, after which it needs to be replaced. You should check how often you will have to replace it. Any filter with a minimum replacement time of more than four months will work fine for you.


#1 RabbitAir MinusA2 Air Purifier

RabbitAir | MinusA2 Air Purifier

  • 6 Stages of purification
  • Ultra-quiet operation
  • Smart sensor to control fan speed
  • Mobile App connectivity
  • Five years of warranty
  • Suitable for large rooms (815 sq. ft.)
  • One can mount it on the wall as well
  • Timer Functionality (using the mobile app)
  • Settings need to be reprogrammed
  • It cannot handle smoke as efficiently as advertised

Only this unit has six stages of the filtration process amongst the shortlisted top 5 products mentioned in the article.

In the first five stages, air is passed through different filters, and there is a negative ion generator at the end.

The placement of filters in the following order:

Pre-Filter > Medium Filter > BioGS HEPA Filter > Customized Filter > Activated Carbon Filter

The addition of a smart sensor to control the fan speed separates the Rabbit Air MinusA2 (and our other top 5 air purifier the COWAY AP-1512HH) from the rest of the air purifier units available in the market.

This sensor automatically adjusts the fan speed after sensing the air quality.

Rabbit Air’s MinusA2 air purifier has a feature of controlling the unit remotely via a Mobile App.

You will have to connect the unit with the app, from which you can easily control while sitting on your couch.

This unit works well in small to large rooms with a maximum coverage of 815 sq. ft.

Rabbit Air’s MinusA2 air purifier wins the hearts of its buyers with a warranty of 5 years.

It makes this unit more reliable, and you can easily trust this unit to have a good life span.

Thanks to its ergonomic design, you can mount this unit on the wall as well. You can hardly find this feature in any other purifier unit in the market.

Although there is no built-in timer functionality in this unit, customer reviews and support Q&A section has shown that one can adjust the timer using their Mobile App, which adds to its benefits.

This unit has a downside as well. You will have to reprogram the settings every time you turn on the unit.

In other words, it can’t restore the previous settings at which the unit was working initially.

Without any doubt, this unit is best in the list when it comes to air purification, but customer reviews show that if you are a smoker, although still effective, then this unit might not handle smoke as well as shown in the advertisement.

Other Great Air Purifiers for Hayfever (Honorable Mentions)

#2 Coway AP-1512HH Air Purifier


Coway | AP-1512HH Air Purifier

  • Four stages of purification
  • Ultra-quite operation (24.4 dB to 53.8 dB)
  • Airflow control – both manual and automatic
  • Warranty ranges from 1 (for internal functional parts) to 3(fans and electronics parts)
  • Timer (1/4/8 hours)
  • Suitable for small rooms up to 360 sq. Ft.
  • Energy Efficient - the fan will automatically stop and set as Eco mode to save energy.
  • Best suitable for the budget.
  • Without the original box, you can’t claim warranty.
  • Its life span is less as compared to other units.

The air in this unit passes through 4 stages of purification.

Same as Rabbit Air MinusA2 Purifier, these units only have two filters before the main True HEPA filter, which increases the life of HEPA filter.

Arrangement of filters in this purifier unit is in the following manner: 

Pre-filter > Activated Carbon filter > True HEPA filter > Vital Ion

While many manufacturers nowadays claim that their purifier units are ultra-quiet, very few give precise data after testing.

The noise level in the case of COWAY AP-1512HH unit is 24.4 dB at low fan speed and 53.8 at high fan speed. Accurate data shows that testing has been done correctly for this unit.

Just like the Rabbit Air MinusA2 unit, this unit also has the feature of automatic fan speed control.

The best part is, you can adjust it manually as well.

Though it doesn’t allow Wifi accessibility as Rabbit Air MinusA2 does, the COWAY AP-1512HH has a timer function which you can set to three time periods (1/4/8 hours).

Although COWAY’s AP-1512HH is a low budget air purifier, it still can cover space up to 360 sq. Ft.

Which is reasonable considering its cost and size.

The sensor in the air purifier unit detects the air quality and automatically turns it off when the desired quality is maintained in the room.

This feature helps in reducing your energy bills, making this unit energy efficient.

When it comes to warranty, the COWAY AP-1512HH air purifier has a confusing policy but here’s how it works.

You can get a 1-year warranty for internal functional parts and three years for electronics and fans. This doesn’t make sense and is a con in our book. 

Three years for the whole unit would be easier for the consumer.

If you are looking for the best air purifier for hayfever on the budget, this should be your choice.

It is the one of the cheapest on our list but with almost the same features as any other expensive unit.

Buyer’s reviews have shown that they do have excellent customer support.

Still, as a heads up, one strict policy to keep in mind is that you should keep the original box (in which the air purifier is shipped in); otherwise, they may not honor the warranty claim.

So, do take care in this regard!

Some buyers have complained about its short life span of 4 months, but that’s the case with only a very small few buyers.

If they are providing a warranty for 1-3 years, you won’t have to worry about it if you keep their original packaging box in a safe place!

#3 Winix 5300-2 Air Purifier

Winix | 5300-2 Air Purifier

  • 3 stage purification
  • Ultra-quiet operation with a noise level of 27.8 dB
  • Five different modes of operation with automatic fan control
  • Plasma-Wave Technology
  • Warranty of one year
  • Poor Customer Support
  • Air quality sensor is not accurate

Just like the LEVOIT LV-H132 Air Purifier, the Winix 5300-2 purifies the air in three stages.

These include pre-filter and an activated carbon filter before True HEPA Filter.

The order of this filter is as follows:             

Pre-filter > Carbon Filter > True HEPA filter

Unlike the others in this list, this unit can operate at five speed modes (sleep, low, mid, high, turbo)

It is mentioneded in the Product description that this device sounds as low as 27.8 dB, but a statement from recent buyers shows that this level reaches to 65 dB while operating at turbo mode.

The addition of Plasma Wave technology adds to the benefits of this unit.

They have placed it after the True HEPA filter, and it can safely remove odor, allergens and other pollutants from the room.

Although this unit comes with a warranty of one year, most of the buyers have been seen complaining about their warranty not being honored.

It was shocking to read the review of the buyer who himself tested this device to check the accuracy of its air quality sensor.

In an experiment, he threw dust near the purifier unit, though the air around the purifier unit was polluted, even then, the sensor shows “good air quality.” This was a one off case though.

People who have recently brought this unit has warned others about their lousy customer support and limited warranty. They don’t quickly pay heed to your return requests.

But the above two scenarios are rare to observe as nearly 80% has given this unit a staggering rating of 5/5*, which means most of the customers are happy with the unit.

#4 Blueair Classic 605 Air Purifier

Blueair | Classic 605 Air Purifier

  • 1-Stage purification
  • Noise level ranges from 32 dB (low speed) to 62 dB (high speed)
  • Warranty of 1 year which can be extended to 5 years.
  • Compatible with Alexa
  • Three fan speeds but no mention of automatic fan control
  • Available in various sizes
  • Can be controlled via Mobile App
  • It can cover space up to 775 sq. ft.
  • No Smart sensors
  • Pesticide-like chemical smell – a pressing issue
  • No timer functionality

When it comes to the filtration process, this unit is unique, with only one “Particle filter.”

Having one filter doesn’t mean you won’t get quality air to breathe; as it is nearly as powerful as the HEPA filters in terms of capturing allergens.

The combination of mechanical and electrostatic filtration doesn’t let allergens as small as 0.1 microns in diameter to pass through this filter.

To battle against gases and odor, BLUEAIR’s Classic 605 recommends using a SmokeStop filter, which serves the same purpose as activated carbon filters.

But, you have to buy it separately with this unit.

Just like the COWAY AP-1512HH, this unit also has been tested properly to determine the upper and lower limit of the noise level.

The operational noise of this unit is 32 dB at low fan speed and 62 dB at high fan speed.

This unit works at three different fan speeds, which is the case for most of the units.

But, there is no mention of automatic fan speed control, which makes it less reliable than the COWAY AP-1512HH and Rabbit Air MinusA2 units, which have this feature.

Its compatibility with Alexa makes this unit unique in the list of air purifiers. You won’t find this feature in any other unit on this list.

You can control the unit via a mobile app as well, just like the Rabbit Air MinusA2 purifier unit. This feature is exclusive in these two units only.

When we talk about maximum area coverage, this unit best matches the Rabbit Air MinusA2 purifier unit.

With an upper limit of 775 sq. Ft. This unit stands second in terms of maximum space coverage.

This unit also comes in different sizes. So, you can select the one that best matches your room size.

Initially, in the description and features section of this unit, there was no information about its warranty.

However, after going through the Customer Q&A section, we have found the company itself is providing a warranty of 1 year. 

Moreover, if you register it with Amazon within 60 days, you will get an extended warranty of 5 years.

Unfortunately, if you are living outside North America, you may not be applicable for this benefit.

There is no additional smart sensor in this unit to control the fan speed by sensing the air quality.

You have to operate this unit in different settings manually. 

This is one of the reasons why it missed out on top spot as the best air purifier for hayfever and other allergies.

When we see a lot of buyers of a certain unit complaining about the same issue, one should take it seriously.

After a thorough look at the recent buyers’ reviews, it is sometimes seen that this purifier unit emits a pesticide-like chemical smell, which doesn’t dissipate for nearly a month.

Unlike the first two purifier units in the list, this unit doesn’t have any timer functionality.

You will have to manually turn it on/off as desired, which is shouldn’t be much of a problem for most of the buyers of this unit.

#5 LEVOIT LV-H132 Purifier

LEVOIT | LV-H132 Purifier

  • Three stages of purification
  • Ultra-quite operation - 25dB
  • Three fan speeds
  • 2 Years Warranty
  • Suitable for small rooms only (139 sq. ft.)
  • Lightweight and portable
  • No Timer Functionality.
  • Hard to claim warranty - customer support issue
  • Don’t create much impact on air quality

The order of this filter is as follows: 

Pre-filter > True HEPA filter > Carbon Filter

This unit has three stages of the filtration process and uses the same filters as the WINIX 5300-2 Air Purifier unit.

The only difference is in the order of placement of these filters. Here, true HEPA filter comes before the activated Carbon Filter, which is opposite in the later unit.

Just like any other unit, this unit also claims to have an ultra-quiet operation with a noise level of 25 dB.

They have not mentioned whether the noise level remains the same at all three fan speeds or not. Buyer’s reviews show that it reaches to 50 dB at high fan speed.

Just like the Blue Air purifier unit, this unit can also operate at three fan speeds with no automatic control.

LEVOIT LV-H132 purifier units can cover an area of 139 sq. Ft. This is by far the lowest area coverage by any air purifier in the list.

This unit has a warranty of 2 years – the lowest as compared to other units in the top 5 picks.

Being small in size, it is very light in weight. You can quickly move it around the house.

It is one of the lightest units available in the market.

Just like the Blue Air purifier unit, you won’t find a timer functionality in this unit.

Many people who have brought this unit in a period of the last two years have complained that activating the unit’s warranty was a tough and tedious process, noting that LEVOIT’s customer support was very slow.

Although this unit is very inexpensive, it won’t purify the air as effectively as other purifier units.

After comparing user experiences, the LEVOIT LV-H132 doesn’t produce the significant difference in air quality as the above four are able to. 

One possible reason could be that users are using this unit in large rooms above 139 sq. ft.
