The 10 Best Air Purifiers for Cat Urine Odor

The best overall air purifier for cat odors is the LEVOIT Compact HEPA Air Purifier. We love its compact size and that it has a three-filter system: a pre-filter, a HEPA, and an activated carbon filter. These three filters are effective at eliminating allergens like pollens, smoke, and dust, as well as pet dander and odors. It’s quiet and provides a gentle nightlight that can be turned off or on when needed. It’s ozone-free and doesn’t use UV-C light, so it uses less energy.

The flaw with this product is that while it is quiet if you keep it in the bedroom, light sleepers might find that it still makes too much noise. Additionally, this unit tends to give off high EMF readings, which isn’t a big deal for most people, but if this is an issue for you, keep shopping.

The best air purifier for cat urine odor for the money is the Germ Guardian Pluggable Small Air Purifier. It’s inexpensive (for an air purifier), and it uses a UV-C light, so you don’t have to worry about replacing filters as often. It plugs into the wall so you can place it close to the source of the odor problem — where the kitty litter is kept, for example. The UV-C light works with titanium dioxide, which also helps reduce airborne viruses and bacteria. The bulb only needs replacing about every 10 to 12 months.

The issues with this air purifier are that it is not that quiet, as the fan seems to make a relatively high-pitched sound. The bulb can also be somewhat physically challenging to replace.

The Rabbit Air MinusA2 Allergy Pet Odor Air Purifier is our premium pick. It has a pre-filter and four other filters: a medium filter, HEPA filter, customized filter, and an activated carbon filter. It gives the option for a customized filter so you can choose the one that you’re the most interested in, such as pet allergies, defense against germs, and odor remover (this model is for odor remover). The motor has five different speeds that are extremely quiet, and it can be mounted on the wall. It works in large rooms up to 815 square feet and traps particles as small as 0.3 microns.

The problem with this air purifier is that it is expensive. The air filter replacements are also relatively expensive.

The Coway Airmega App-Enabled HEPA Air Purifier is a powerhouse because it can cover 1,560 square feet and it can clean the air about two times in an hour. It has a true HEPA- and activated charcoal-combined filter and a washable pre-filter. It also has a pollution sensor that indicates how clean or dirty your air is at all times, and the fans adjust accordingly. The fan has five modes — smart, sleep, low, medium, and high — and is super quiet at the lower speeds. It has a timer with four settings (1, 2, 4, and 8 hours) and includes a mobile application for extra settings and support.

However, there are issues with the app and connectivity, and for some customers, it might be more hassle than it’s worth. Also, it is quite expensive.

The Hamilton Beach TrueAir Air Purifier has three filters — a true HEPA and two carbon zeolite filters, as well as a pre-filter. The two activated-carbon filters help reduce strong odors, and it’s quiet while it works hard with three settings (low, medium, and high). The HEPA filter is permanent, so it doesn’t need to be replaced and can be easily vacuum cleaned. The purifier can be placed either horizontally or vertically to better fit the space.

However, while the lowest speed is quiet, it gets progressively louder as you turn it to the higher settings. While the HEPA filter doesn’t need replacing, you still need to replace the two carbon zeolite filters.

Alen’s BreatheSmart Flex True HEPA Air Purifier is attractive and has an activated=carbon filter that is 0.66 pounds, so you know that it means business against strong odors. It also has a true HEPA filter, which is medical-grade and removes 99.99% of viruses and bacteria. It can clean a 700-square-foot space every 30 minutes, and it has a lights-out mode for while you’re sleeping.

The issues here are that it’s expensive and that compared to many other air purifiers, it’s fairly large.

The Honeywell InSight HEPA Air Purifier uses a HEPA filter to remove 99.7% of allergens in rooms that are 500 square feet. It has an activated-carbon pre-filter that reduces odors, and it cleans the air 4.8 times in an hour. It has an air-quality indicator that will let you know at a glance if your air quality is good, moderate, or bad and automatically adjusts to the proper cleaning level.

The issues here are that it is relatively expensive and that on occasion, it might make a rattling sound. It’s less than quiet at times.

Bissell’s MyAir Air Purifier is a personal purifier because it’s small enough to be placed on your desk or table and is quiet. It includes a pre-filter and activated-carbon and high-efficiency filters. It has three speeds, including a sleep fan, which is quieter. It also has a nightlight that can be turned off.

The problems with this purifier are that it can be loud at the highest level and that it doesn’t have a medium setting. Just sleep, low, and high.

The Lasko HEPA Filter Room Air Purifier has a true HEPA filter and a carbon-activated filter that traps 99.7% of airborne pollutants. It has three speeds, an 8-hour timer, and a notifier if your filter needs changing. It can clean a small room in about 10 minutes, and its digital display makes using and reading it easy.

The issues are that the door for the filter doesn’t always latch properly and that it isn’t the quietest air purifier. Plus, for its ability to only treat small rooms, it’s relatively large and heavy.

Germ Guardian’s HEPA Filter Air Purifier has a pre-filter, an activated-charcoal filter for those nasty odors, and a true HEPA filter for air pollutants. It’s been treated with an antimicrobial agent that can prevent mildew and mold from forming on the filter, so the purifier itself will remain odor-free. You also have the option of using a UV-C light, which helps eliminate airborne viruses and germs. It has an 8-hour timer, a filter change indicator, and five-speed settings.

The problems with this purifier are that it can be noisy, especially at the highest speeds, and that sometimes one of the vents seems to stop working and only blows air from one side. Plus, if allergies are an issue, it doesn’t always seem to help allergy sufferers.

Buyer’s Guide: Selecting The Best Air Purifier for Cat Urine Odor

Now that you’ve learned about the various air purifiers out there, check out this buyer’s guide before making a final decision. We cover a few points for you to think about and hopefully, to help you understand what you should be looking for in an air purifier, particularly for helping reduce cat urine odors.

Room Size

You should an idea of how much space you want the air purifier should cover. Did you want to only place the purifier near the kitty litter box, or did you want it to cover a larger area? Measure the space, and double-check the description of the purifier to ensure that it will cover the desired area. Also, make sure to read reviews, as other customers will likely mention how large a space it seems to cover. In some cases, you might need to buy more than one.

Filters

Once you’ve paid for the actual air purifier, don’t forget that purchasing filters is an ongoing expense, so it doesn’t just stop with the actual purifier. Specifically, you should ensure that the air purifier has an activated carbon filter for reducing odors. Many air purifiers also have HEPA filters because they are designed for people with allergies, so you’ll get the added advantage of fewer air pollutants and reduced stinky odors.

Cost

Unfortunately, the idea that you get what you pay for isn’t always true. Air purifiers can be quite expensive, but one that is hundreds of dollars doesn’t guarantee that it works the best. Read reviews to get a better idea of whether the purifier you’re considering will work for your needs.

Noise

Some air purifiers are whisper quiet, while others sound like a jet taking off. If you don’t plan on having it in your bedroom, a noisy unit that does a great job at reducing odors may be fine, particularly if it saves you money. But keep in mind that if you’re placing a noisy purifier next to your cat’s litter box, your cat might not be too impressed and could start avoiding the litter box altogether.

Conclusion

The LEVOIT Compact HEPA Air Purifier is our overall favorite air purifier. We love its compact size and its three-filter system that works well at reducing nasty odors. For value, the Germ Guardian Pluggable Small Air Purifier is inexpensive. It uses a UV-C light, so you don’t have to worry about replacing filters. Lastly, the Rabbit Air MinusA2 Allergy Pet Odor Air Purifier is our pick for premium choice because it has five efficient filters and is quiet and efficient.

We hope that all these reviews have helped you find a good air purifier or at least given you a better idea of what to look for. Reducing the smell of cat urine is important because we all know how awful that odor can be, and a good air purifier should definitely help.
