The air in this purifier unit passes through 5 different stages of purification, which makes it unique in this best purifier for Pulmonary Fibrosis list.

Filters are placed in the following manner:

Cold Catalyst Filter > Activated Carbon > Antibacterial Filter > HEPA Filter > Ionizer

The function of their cold catalyst and antibacterial filters are explained below:

Cold Catalyst filters – deal with large dust, pet dander, pollen and mold

Antibacterial filter – as the name suggests kills bacteria and germs

(To find out more about how different filter types work, check this out)

This unit operates quietly with a maximum noise level of 43 dB. At sleep mode, this value is below 20 dB.

Just like the Medify MA-40W Air Purifier (later in this list), Hathaspace’s HSP001 comes with an air quality sensor.

So, the fan speed is automatically adjusted according to the air quality.

The area coverage for this unit is 350 sq.ft and a great feature we loved was its 48 times per day air circulation (twice per hour) function.

The Hathaspace Smart Air purifier comes with an 8-hour programmable timer as well, but you’ll have to reprogram it once it’s powered off.

This unit is also certified with CARB proving it to be Ozone-free.

Wifi Accessibility allows you to control the settings remotely without moving a single step.

Although this unit has a limited warranty of two years, which is by far the least in comparison to other units, this device has been the most LOVED by buyers.

Moreover, one must praise HathaSpace for installing an efficient air quality sensor in this unit.

We tried spraying different solutions into the opposite corner of which the air purifier was placed, and the sensor automatically sensed them and turned on automatically. After removing the smell, it went off again.


One buyer has complained about the purifier fan slightly off-balanced. So, just for the heads up, you should check it at the time of arrival of the unit although this seems to be an isolated case.

This unit supports 110 V, and few buyers who have connected it with 220 V power supplies have burned the unit.

So, it is advised to run it at 110 V where possible.

Their Customer Support team has mentioned that they will include a step-down transformer switch to cater to this problem, but it is not clear whether they have added this feature in new units or not.

Although it is certified with CARB, which states that it is Ozone free, one of the buyers has complained that when she turns the ionizer on, she sensed the Ozone in the air and confirmed it with an ozone detector.

Thankfully, this was the case with only one buyer as well.

Other Great Air Purifiers for Pulmonary Fibrosis (Honorable Mentions)

#2 Medify MA-40W V2.0 Air Purifier

Medify | MA-40W V2.0 Air Purifier

  • Four stages of filtration system
  • Medical Grade H13 True HEPA
  • Ultra-quiet Operation
  • Quality Control Sensor
  • Coverage area up to 1600 ft2
  • Lifetime Warranty
  • Handles Wildfire smoke efficiently
  • Night Mode and easy to clean
  • No Ozone Generator
  • Child Lock Functionality
  • Filter shipment can time
  • Not for light sleepers

With four stages of the Filtration Process, this unit is one of the best in terms of purifying the air with its powerful H13 True HEPA filter.

The H13 True HEPA is an advancement of HEPA filters, and it only passes 0.05% of 0.1-micron particles per liter of air.

In short, it edges out standard HEPA filters used in other devices.

Filters are placed in the following order:

Pre-Filter > H13 True HEPA Filter > Activated Carbon Filter > Ionizer

The three filters are placed in a single cartridge, which makes the replacement and cleaning process more comfortable.

Like most of the air purifiers in the list, this unit operates at three fan speed settings.

As indicated by the Medify, the noise level at maximum fan speed cannot exceed 66 dB for this unit.

One buyer moved one step further and measured the unit’s noise levels using NIOSH mobile app, and at each fan speed, the noise level was 52, 62, and 65 dB, respectively.

Of course, actual noise will be much lower when measured with the noise meter.

Overall, most buyers have been happy with the unit’s volume levels.

This air purifier is also equipped with an air quality sensor that adjusts the fan speed after sensing the quality of air inside the room.

Apart from this unit, only the Hathaspace Smart Air Purifier has this sensor in this list.

It can be used for areas up to 1,600 sq. ft, and with a CADR of 330, it is able to complete one full air circulation in an hour.

This means that in a smaller room of half the size (840 sq. ft), the time for whole room air purification is 30 minutes, and in 420 sq. ft, one circulation would just take a time of 15 minutes Superb!

Medify offers a lifetime warranty for this unit which builds trust and increases its reliability.

However, you’ll have to replace the filters every six months or after 2500 hours of usage.

Otherwise, they may not owner the warranty - Shouldn’t be a big issue since the filters have eventually to be replaced regardless.

If you live in areas where you have to deal with wildfire smoke quite often, then this unit is for you. Buying this unit will help you get rid of this worry.

When you put this unit on night mode, the ionizer automatically turns off, and you can have a sound sleep.

Additionally, its easy to clean tempered glass panel give this unit an edge over other purifier units whose casing is made up of plastic mostly.

This unit is certified with CARB, Energy Star & ETL, which adds to the reliability of this unit.

An ozone-free air purifier is what you should be looking for to deal with Pulmonary Fibrosis. And this unit is one that has no Ozone generator.

Ozone can cause damage to the lungs, so all selected units are ozone-free.

If you are a busy parent and you have naughty kids that may disturb the settings unknowingly, there is a child lock function on this air purifier.

Since this unit is highly reliable and has a lifetime warranty, it doesn’t have many drawbacks.

Although, one buyer has previously complained about its air quality sensor not working.

Not an issue as the best part is, Medify has sent that buyer a new sensor with a proper guide of how to change it with the old one - simply great customer service!

Although the product shipment is speedy, they take more than two weeks to ship the filters.

So, you should order the filters one month before their expiry date.

#3 Germ Guardian Air Purifier

Germ Guardian | Air Purifier (AC5350B)

  • Three stages of purification
  • 5 Fan Speed Settings
  • Five years warranty
  • UV-C light
  • It is loud and disturbing at 3-5 fan settings.
  • No Air Quality Sensor
  • Support Germs Guardian filters only

Air is passed through only three stages during the filtration process, and there is no built-in ionizer in this unit. However, the MOOKA Air Purifier’s UV-C light helps in killing airborne viruses and bacteria to make your home a haven for you. This feature is not present in any other purifier unit other than MOOKA Air Purifier.

Placement of filters are as follows:

Pre Filter > True HEPA filter > Activated charcoal Filter

This unit operates at five different fan speed settings, which you won’t find in any other purifier unit.

However, it is recommended by the buyers to use this unit on only the first three settings as the unit gets noisy while operating in the 4th and 5th setting.

In terms of area coverage, this device is limited to a 167 ft2 room. It is the smallest coverage by any purifier in the top 5 picks.

With its five years of warranty, this unit gives the second-best warranty in comparison to the other four purifier units with Medify MA-40W Air Purifier still on top.

There is no official data about the noise level, but according to data given by the buyers, the noise level for this unit can exceed 60 dB at 3-5 fan settings, with a rattling sound being the most disturbing for buyers.

Just like MOOKA Air Purifier and Honeywell HPA200 Air Purifier, this unit also doesn’t have an air quality sensor. 

So, for all these units, you have to control the fan speed manually.

Many buyers have complained about its short life span, which is a bit alarming.

Although their customer support is very helpful, the unit itself may not last as long as the others in this list (bearing in mind that it’s still one of the top 5 air purifiers available for pulmonary fibrosis).

A con of this unit is that you it’s only compatible with filters produced by this company.

Secondly, the time for replacement is 6-8 months. Which, if not replaced in good time, you will see a drop in the performance of the purifier unit.

#4 MOOKA Air Purifier

MOOKA | Air Purifier (EPI810)

  • 3 Stages of Filtration
  • Ultra-Quiet Operation
  • Three years warranty
  • CARB Certification
  • 3600 Air Intake and Discharge
  • Efficient handling of smoke
  • UV-C Air Sanitizer
  • No Air Quality Sensor.
  • No data about multiple fan settings
  • No Built-in timer

Just like Germ Guardian Air Purifier, this unit also has three stages of filtration, and the filters are placed in the following order:

Pre-filter > True HEPA filter > Activated Carbon Filter

In night mode, operating noise level is below 35 dB – thanks to its noise-reducing fan blade design.

This unit covers rooms up to an area of 215 ft2 making it ideal for small to medium sized rooms

Similar to the Medify MA-40W Air Purifier and Hathaspace Smart Air Purifier, this unit is also certified by CARB, which means its operation is ozone-free.

Although Ozone can strengthen the air cleaning process, it can greatly affect people suffering from lung diseases and pulmonary fibrosis.

Its round design makes the air intake and discharge process uniform, and the distribution of air is smooth in all directions.

This unit can handle smoke efficiently, making it another great option in wildfire smoking handling.

Its UV light will kill any bacteria or viruses that pass through the primary HEPA filter. This feature lets this unit compete with the other top air purifiers in the market.

On downside is that this unit doesn’t have any air quality sensor.

Furthermore, unlike the rest of the purifier units in the list, this unit doesn’t have any timer.

#5 Honeywell HPA200 Air Purifier

Honeywell | HPA200 Air Purifier

  • Two stages of purification
  • Ideal for small to medium rooms
  • Five years Warranty
  • AHAM Certified
  • Not for light sleepers
  • Smartphone compatible functions leave more to be desired
  • No Air Quality Sensor
  • Plastic Smell

With two stages of purification using the A+ Genuine Pre-Filter and R Certified True HEPA filter, this unit is similar to the MOOKA Air Purifier and Germ Guardian Air Purifier in its ability to purify the room air and a reliable unit.

Filters are placed in the following arrangement inside the purifier unit:

A+ Genuine Pre-filter > R Certified True HEPA Filter

You have to replace the Pre-filter after every three months and HEPA filter once in a year.

This unit can work at four different fan settings (Germ Setting, General Clean, Allergen, and Turbo), and covers up to 310 ft2, which makes it a suitable choice for small to medium sized rooms.

That being said, in the stated area, this unit circulates the fresh air five times in one hour.

Meaning this unit can be used for large rooms as well, just with less air circulation per hour.

The Honeywell HPA200 Air Purifier has a programmable timer of 8 hours as well.

Just like the Germ Guardian Air purifier unit, this unit also gives a 5-year warranty.

With AHAM certification, this unit stands in the list of trusted and reliable air purifiers.

In terms of its noise levels, a buyer’s measured noise for each different setting, from a distance of 3 feet (1 meter), came out to be 43 dB (Germ Settings), 47 dB (General Clean), 53 dB (Allergens), and 58 dB (Turbo).

With the lowest Noise level of 43 dB, this unit is moderately noisy and may not be the best unit for light sleepers.

As there is no quality control sensor, you will have to adjust the fan speed manually.

On the smartphone compatibility front, its Bluetooth control and accessibility via app makes this unit unique from rest.

However, buyer’s reviews show that the Bluetooth accessibility may not work properly at times, and that accessibility via their app might not perform well on iOS.

Users reported facing glitches during operation and insufficient app updates.

Some buyers have also previously complained about the lingering of plastic smell.

Upon contacting the support, they were told to air the unit outside for 40-50 hours -of which, the smell didn’t go away.

Likely a problem with that batch of purifier production only but worth looking out for and taking into consideration.

What to Consider When Buying the Best Air Purifier for Pulmonary Fibrosis

Filtration System

The performance of any air purifier unit mainly depends on the efficiency of the filtration system.

Harmful contaminants after filtered from the air after passing through different stages of the purification process, and at each stage, there is a filter that serves a specific purpose.

The most common type of filters used in the air purifiers includes HEPA filter, pre-filter, activated carbon filter, ionizer, UV Lights, and ozone generators.

The HEPA filter is considered as the best air filter as its absorbent material can capture allergens as small as 0.3 microns in diameter with an efficiency of 99.97.

The functioning of each of these filters is explained below:

  • Pre-filters - Large dust particles, including hair, fibers, and large particle, e.g., dander, are captured by the Pre-filters resulting in prolonging the life of HEPA filter.
  • Carbon filters - The smell of smoke, cooking, and other odorous particles can cause irritation for a person suffering from Pulmonary Fibrosis. The activated carbon filter does this task of removing these odors.
  • Ionizers - As the name suggests, charges small dust particles with a negative ion, which are then collected in a positively charged plate.
  • Ultra-violet lights - They kill the bacteria and other harmful viruses which increases the purifier efficiency.
  • Ozone generators - They 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 the case of selecting the air purifier for Pulmonary Fibrosis, we would suggest you should make sure that there are no ozone generators in the unit.

If you are interested in learning more about the functionality of each filter, you should refer to this article.

Version of the Air Purifier

After choosing the right filtration system for the purifier unit, the next thing to keep in mind is the version of the air purifier. All air purifiers are either categorized as ‘classic’ or ‘smart.’

Classic air purifiers – They are designed just to clean the air typically without measuring the nature and quantity of pollutants removed by the air purifier unit in real-time.

Moreover, they are not equipped with modern sensors and control systems.

The absence of necessary data can makes it difficult to have an idea about the effectiveness of the unit, and the only thing you can do if you wanted to measure the air quality is to use an air quality meter like this one.

Smart Air Purifiers - On another side, “smart” air purifiers tackle all your worries of performance measurement.

With air quality sensors, digital controls, and even mobile app connectivity for some, these units give you data of pollutants being removed.

You could even measure your farts if you wanted to INSERT this video of man farting into air purifier.

These features allow us to measure the performance of the air purifier unit effectively (and one can replace the unit if it fails to perform in the same way as advertised by the manufacturer).

In this case, while selecting the best air purifier for Pulmonary Fibrosis, you don’t have to worry about this factor. We have made a choice easier for you by selecting all those units which fall in the category of 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

Lastly, filter replacement is the one of the most annoying parts for most people.

Sometimes, people forget about the replacement date as well, and continue using the same filter even after its expiry time.

This would render it ineffective in its efforts to purifier the air for our homes!

Some units have filter replacement indicators that remind us about the expiry of the units filter.

In more contaminated places, filters can become clogged and require replacements way before their expiry date. Having an indicator can help in this case by giving us an early heads up!

Typically, the filter indicator LED will start glowing when it’s almost time and time for a replacement.

To maximize the usage of the filters, we would suggest checking it at least twice a week when the expiry date is near.

Other Factors

  • Programmable Timer: People often forget to turn these units on/off throughout the day. Having a programmable timer can solve this problem.
  • Multiple Fan Speeds: Having a unit with multiple fan speeds or even a sensor that automatically adjusts its speed offers greater customizability.
  • Noise Level: Running the fan on high speed can cause significant noise. Check the maximum noise level that the unit produces before buying it.
  • Frequency of Filter Replacement: Filters in the unit needs replacement after every 4-8 months which add to the cost.
