URI's are a disease caused by a virus and this virus usually emerges in cats during stressful periods or situations.

The most common symptoms of an upper respiratory infection are sneezing, runny eyes and nose, and congestion; however, this disease can also lead to serious consequences in certain cats.

A humidifier can potentially help ease these symptoms and make it easier for your cat to breathe.

What to Consider When Buying the Best Humidifier for Cats with URI

What to Consider When Buying the Best Humidifier for Cats with URI

In order to choose the best product for you and your cat, you’ll first need to consider a couple elements.

Here is a quick list of the main factors you should consider before making a decision and settling on a specific humidifier:

  • Adjustable mist levels: A cat with URI is going to be more sensitive to changes in the environment; therefore the humidifier you plan on buying should make it possible for you to make adjustments to the output at any time – the more precise, the better when calibrating for your cat.
  • Autonomy: There may be instances when you won’t be able to spend the whole day with your cat and tend to its needs constantly. A humidifier should have a good amount of water autonomy so that it can run for several hours straight without needing any refills.
  • Silent mode: To avoid your cat being bothered by the noise of the device, check if the unit you’re looking at is equipped with a silent mode or a night mode.

Other factors:

  • Refilling and cleaning mechanism: Before you buy a unit, check how easy it is to refill and clean.
  • Maintenance: Is the humidifier going to need expensive maintenance? Does it need any filters? How much do the filter costs? These are all questions you should ask yourself to avoid facing unexpected expenses later on.
  • Water types: Some humidifiers can only be filled with distilled water, while others can potentially be filled with any type of water. While tap water is more convenient, using distilled water is usually recommended to avoid the formation of white dust on your surfaces, which can be harmful for both you and your cat. Therefore, remember to check if the unit is compatible with regular tap water.


#1 Air Innovations Humidifier (MH-901D)

Air Innovations | MH-901D

  • Great autonomy
  • Large tank
  • Dual direction nozzle
  • Remote control
  • Silent mode
  • Programmable timer
  • Cheap maintenance
  • Need to use distilled water to avoid white dust
  • May need to be further secured if you have playful/curious cats

With a 6.6L (1.6 gallon) water tank, the Air Innovations humidifier offers one of the largest water capacities you can find and with a massive 100 hours run-time.

Among the device’s main features, we found it to be effective in dispersing moisture to rooms thanks to its dual direction mist nozzle that spreads mist evenly in large rooms, an auto shut-off safety measure that automatically turns off the humidifier when it runs out of water, and remote control to comfortably adjust the settings from afar.

Furthermore, the unit includes 5 levels of mist output, a programmable timer you can set whenever you’re not home with your cat, and the option to turn on the night mode to eliminate most of the noise produced.

In terms of refilling, the process is rather simple: lift the lid and pour water inside.

Keep in mind that to avoid any white dust spreading, it’s better to use distilled water instead of regular tap water for this humidifier.

Cleaning the unit isn’t a lengthy process, but it’s recommended doing it quite often, especially to prevent the growth of microbes and protect your cat’s health.

As a last feature, we’d like to mention the filter is made of ceramic and it’s permanent, meaning that the maintenance costs of the device are going to be rather cheap.

One thing to take note of is the placement of this humidifier.

Because of its design, we would suggest placing the unit against wall or securing it well to avoid having it tipped over by curious or playful cats.

Other Great Humidifiers for Cats with URI (Honorable Mentions)

#2 Elechomes Warm and Cool Mist Humidifier (SH8820)

Elechomes | SH8820

  • 3 mist levels
  • Warm or cool mist option
  • Easy to refill
  • Silent mode
  • Remote control
  • One can accidentally ruin it while cleaning it
  • The autonomy is greatly reduced when set on high

When looking for a humidifier for your cat who has URI, this Elechomes model is definitely a good option.

It is equipped with a 5.5L (1.45 gallon) tank that can guarantee 12 to 40 hours of run-time without needing a refill.

The device is able to produce either warm or cold mist, depending on your cat’s needs, and it pumps mist in all directions thanks to two rotating nozzles.

The whisper quiet mode prevents the unit from bothering more sensitive cats and, if it sleeps in your same room, you can also make good use of the screen-off mode to eliminate all light coming from the device.

As for the humidifier’s refilling method, it’s well designed and you’ll be able to add water to the tank without any disassembly.

More specifically, you’ll just have to lift the top cover and pour water inside whenever needed.

However, we cannot say cleaning the device is as easy as refilling it.

This is because when one tries to clean it, there’s always the risk of spilling water into the unprotected electronic parts, and resulting in the ruining of the humidifier.

The device comes with a remote-control feature and 3 different mist outputs to choose from, making it easy to use, and, last but not least, the replacement water filters are affordable.

#3 Pure Guardian Ultrasonic Humidifier (H4750AR)

Pure Guardian | H4750AR

  • Up to 120 hours of autonomy
  • 3 speed levels
  • Auto shut-off
  • Night mode
  • Low water indicator
  • No filter required
  • Hard to refill
  • Can’t be placed on carpets

Here is a humidifier that, thanks to a 7.5L (2 gallon) tank, can work for a massive 120 hours straight when set on low, without needing a single refill.

In other words, it’s good if you spend most of the day outside your house and often forget to add water to the device.

However, when you do need to refill it, some disassembly is going to be needed because the tank fills from the bottom.

With this humidifier, you’ll be able to choose between three speed settings, depending on how much mist output your cat needs, and the low water indicator will immediately let you know when the unit needs a refill.

As for the previous units, the humidifier also includes an auto shut-off feature to protect it from damage caused by running the unit without water, and a night mode which is designed to reduce the device’s noise.

What makes this unit stand out is that it doesn’t need any filters, meaning maintenance costs will be very low.

Moreover, a “silver clean protection” prevents the formation of slimy mold on the surface of the tank so that neither you nor your cat will have to breathe any impurities coming from the humidifier.

On a last note, avoid placing the unit directly on carpets or blankets as the area around it can become quite moist.

More specifically, the unit needs to be elevated from the ground to prevent the formation of mold.

#4 Pure Guardian Ultrasonic Cool Mist Humidifier (H3200BAR)

Pure Guardian | H3200BAR

  • 3 mist levels
  • Great autonomy
  • Easy to clean
  • Low water indicator
  • No filters needed
  • Auto shut-off
  • Not suited for large rooms

Here is another humidifier that offers up to 100 hours of run time thanks to a 5.7L (1.5 gallon) tank, and silver clean protection to prevent the growth of bacteria and mould inside of it.

Where the other humidifiers on this list were suited for large rooms, this unit works better in small to medium sized environments.

Among the main features of this device, one of the best advantages is that it doesn’t need any filters.

Since the base portion is smaller compared to other humidifiers, refilling and cleaning the device is rather easy as well and you’ll be fine just by using a wet wipe and some vinegar for the hardest parts.

#5 TTLIFE Warm & Cool Mist Humidifier (12-40H)

TTLIFE | 12-40H

  • Different mist outputs
  • Remote control
  • Night mode
  • Constant humidity mode
  • Easy to refill
  • Permanent filter
  • Run-time is greatly reduced if set on high

While this device’s autonomy isn’t among the longest compared to other humidifiers on this list, the unit still offers up to 40 hours of run time without refills thanks to a 4L (1 gallon) tank.

Keep in mind that if you intend to use the humidifier on a high mist output, then the run-time will last a lot less.

The TTLIFE 12-40H is able to produce warm and cool mist even when night mode is turned on, and, thanks to a remote control, you’ll be able to adjust these settings from afar.

What we found great about this unit was its smart constant humidity mode which automatically adjusted the humidity levels when it dropped too low.

This takes some burden off you to constantly monitor the humidity levels for your cat. Mist was evenly spread too with its dual rotating nozzles.

In terms of refilling, the TTLIFE 12-40H is easy and refilled from the top by lifting the lid, detaching the tank, and adding water.

Whenever you need to clean the device, you’ll just need to repeat the same process and easily rinse out the tank.

Last but not least, this humidifier comes with a permanent filter that doesn’t need to be replaced as long as you clean it regularly.
