The 8 Best Air Purifiers for Cat Urine Odor
1. LEVOIT Compact HEPA Air Purifier — Best Overall
| Size: | 8.5 x 8.5 x 14.5 inches |
| Color: | White |
| Room Size: | 128 square feet |
The best overall air purifier for cat urine odor is the LEVOIT Compact HEPA Air Purifier. It has three effective filters: a pre-filter, a HEPA filter, and an activated-carbon filter. These work together to reduce airborne allergens like dust, pollen, smoke, and pet dander, as well as strong pet odors. It’s quiet and has a nightlight that can be turned off or on when necessary. It also doesn’t use a UV-C light, is ozone-free, and doesn’t require that much energy to run.
There are a couple of flaws with this air purifier, though. It is a quiet product, but you might find that it still makes too much noise at its highest setting, particularly if you have it in the bedroom and you’re a light sleeper. Also, this purifier seems to emit high EMF readings, which aren’t harmful, but if this is a problem for you, you should look elsewhere.
All in all, we think this is the best air purifier for cat urine odor that you can buy this year.
- Compact in size
- Three effective filters
- Low energy use
- Ozone-free
- Quiet and has a nightlight
- The highest setting might be too loud for a bedroom
- High EMF readings
2. Germ Guardian Pluggable Small Air Purifier — Best Value
| Size: | 2.75 x 3.5 x 6.75 inches |
| Color: | Black or White |
| Room Size: | 56 square feet |
The best air purifier for cat urine odor for the money is the Germ Guardian Pluggable Small Air Purifier. It’s one of the cheapest purifiers out there but works quite well as a personal air purifier. It uses a UV-C light, so there are no filters to change or purchase. You can plug it directly into an outlet and place it in the area with the biggest odor problem. The UV-C light uses titanium dioxide, which reduces airborne bacteria and viruses. The bulb just needs replacing every 10 to 12 months, depending on use.
The problems with this purifier are that the bulb can be fairly challenging to replace, and it isn’t that quiet—the fan might emit a somewhat high-pitched sound.
- Well-priced
- Uses UV-C light rather than filters
- Can plug it in next to the bad odor
- Uses titanium dioxide to reduce viruses and bacteria
- Might make a high-pitched noise
- The light bulb can be difficult to change
3. Rabbit Air MinusA2 Allergy Pet Odor Air Purifier — Premium Choice
| Size: | 20 x 7 x 21 inches |
| Color: | Black or white |
| Room Size: | 815 square feet |
The Rabbit Air MinusA2 Allergy Pet Odor Air Purifier is our pick for a premium choice. It comes with five filters: a pre-filter, HEPA, a medium filter, a customized filter, and an activated-carbon filter. The customized filter gives you the option to choose a filter of your choice for such issues as the elimination of germs, allergies to pets, or odor remover (the purifier available on Chewy is just for odor removal). It has five speeds to choose from that are all designed to be quiet, and it can be mounted on a wall. It is powerful, and it can purify the air up to 815 square feet and trap the smallest particles at 0.3 microns.
The issues with this purifier are that it is quite expensive and that the replacement filters are fairly costly.
- Five filters
- Option for specialized filters
- Five quiet speeds
- Can be wall-mounted
- Purifies up to 815 sq. ft.
- Expensive unit
- Costly filters
4. Coway Airmega App-Enabled HEPA Air Purifier
| Size: | 14.8 x 14.8 x 22.8 inches |
| Color: | Graphite or white |
| Room Size: | 1,560 square feet |
The Coway Airmega App-Enabled HEPA Air Purifier covers the largest square footage of all the filters on this list at 1,560 square feet. It cleans the air about twice every hour and has true HEPA and activated-charcoal filters combined with a washable pre-filter. It has a pollution sensor that lets you know how clean or dirty the surrounding air is and adjusts itself automatically. It has five speeds: smart, sleep, low, medium, and high. It is very quiet at lower speeds. It also has a timer with four settings and includes a mobile app that gives you further options and support.
The problems here are that it is expensive and that the app sometimes has issues with connectivity, which can be a bit of a hassle to deal with.
- Covers 1,560 sq. ft.
- Combined charcoal and HEPA filter
- Includes pollution sensor that automatically adjusts
- Five speeds that are quietest at the lowest speeds
- Mobile app for support and timer with four settings
- Expensive
- The app has issues at times
5. Hamilton Beach TrueAir Air Purifier
| Size: | 7.62 x 7.3 x 7.96 inches |
| Color: | White |
| Room Size: | 100 square feet |
The Hamilton Beach TrueAir Air Purifier has three carbon filters for thorough air purification, plus an optional scent cartridge. This air purifier works well to reduce strong odors and has a surprisingly quiet motor. It also has two-speed levels and comes with a one-year warranty.
The main flaw is that while the low speed can be quiet, the purifier gets louder as it gets turned up to the higher setting. Also, there isn’t a HEPA filter, and you must purchase replacement carbon filters.
- Three carbon filters for strong purification
- Has a surprisingly quiet motor on low setting
- Two-speed settings
- One-year warranty
- Gets louder at the highest settings
- Carbon filters need replacing
- No HEPA filter
6. Honeywell InSight HEPA Air Purifier
| Size: | 25 x 22 x 13.5 inches |
| Color: | Black |
| Room Size: | 500 square feet |
Honeywell’s InSight HEPA Air Purifier works in spaces of 500 square feet, with a HEPA filter that can remove 99.7% of allergens. It has an activated-carbon pre-filter that can help eliminate odors and clean the surrounding air around five times an hour. It has an air quality indicator that tells you when your air quality is good, moderate, or bad and will automatically adjust to fix any issues.
The problems with it are that some of the units are prone to making a rattling noise and that it’s somewhat expensive.
- Cleans 500 sq. ft. almost five times an hour
- HEPA filter removes 99.7% of allergens
- Activated carbon pre-filter eliminates odors
- The air quality indicator notifies about the air quality and adjusts automatically
- Might make a rattling sound
- Somewhat expensive
8. Lasko HEPA Filter Room Air Purifier
| Size: | 10.3 x 7.3 x 21.64 inches |
| Color: | White |
| Room Size: | 170 square feet |
Lasko’s HEPA Filter Room Air Purifier has carbon-activated and HEPA filters that effectively trap 99.7% of pollutants found in the air. You can pick from three speeds, and there’s an optional 8-hour timer. The purifier notifies you when you need to change the filter, and it has an easy-to-read digital display. It can clean a 170-square-foot area in about 10 minutes.
Some of its problems include that it isn’t quiet and that while it can only treat small areas, it’s quite large and heavy. Also, the door for the filter can sometimes have problems with latching and staying closed.
- Carbon and true HEPA filters remove 99.7% of air pollutants
- Has an 8-hour timer and three speeds
- Notification when the filter needs changing
- Cleans 170 sq. ft. in 10 minutes
- Can be noisy
- The filter door doesn’t always stay closed
- Heavy and large
9. Germ Guardian HEPA Filter Air Purifier
| Size: | 11 x 6.75 x 27.25 inches |
| Color: | Charcoal gray |
| Room Size: | 180 square feet |
Germ Guardian’s HEPA Filter Air Purifier has a true HEPA filter, activated-charcoal filter, and pre-filter for air pollutants and bad odors. The filters have been treated with an antimicrobial agent that helps prevent mold and mildew from forming, which stops the air purifier from contributing to bad smells. It has an optional UV-C light to remove airborne viruses and germs, a filter change indicator, and an 8-hour timer.
However, this purifier tends to be noisy, particularly at the highest speeds, and in some units, one of the vents might stop working, so you’ll only get clean air blowing from one side. Additionally, if you’re also looking for a purifier as an allergy sufferer, this one might not prove as effective as some others.
- Includes pre-filter, HEPA, and charcoal filters
- Filters treated with an antimicrobial agent to stop mildew and mold
- Optional UV-C light helps remove bacteria and viruses
- Has an 8-hour timer, filter change indicator, and five speeds
- Can be loud at high speeds
- One vent might stop working
- Might not be that effective for allergies
Buyer’s Guide: Finding the Best Air Purifier for Cat Urine Odor
This buyer’s guide has extra information to enable you to make a more informed decision. There are various points for you to consider so you can figure out what kinds of features you should be on the lookout for when shopping.
Room Size
The first thing to consider is how large an area you would like the air purifier to cover. Are you looking for a small one that will be situated near the litter box itself, or do you want it to cover a large room? Be sure to measure the area that you want to use it in, and then read the description of the purifier carefully so you know if it can do the job. You should also read reviews by other customers, as they’ll likely mention how big of a space it works in. For a large area, you might need to think about purchasing more than one.
Cost
Air purifiers tend to be fairly expensive. The most expensive ones aren’t necessarily going to do a better job than the cheaper ones, but most of the time, you do get what you pay for. Always take the time to read the reviews, but keep in mind that what doesn’t work for one person could be perfect for you.
Filters
While the initial cost of the air purifier can be high, remember that the costs don’t end there. Some air purifier filters are permanent and only need cleaning, but other filters need replacing, usually every 3 months, depending on the filter. Specifically for odors, your air purifier should also have an activated-carbon filter.
Noise
Most purifiers are made to be quiet, but some can get noisy when working at higher speeds. If you’re not planning on putting the purifier in your bedroom, you might not mind that it isn’t quiet. However, if it’s sitting next to the litter box and rattling around, your cat might be less than impressed. The more expensive purifiers tend to be quieter, but this isn’t a guarantee. Customer reviews are ideal to check out in this case.
