Pets are a joy to be around, but it is hard to deny that they can have a profound impact on our respiratory health and the quality of the air we breathe at home. Cats, dogs and other furry creatures are a major source of hair, unpleasant odors and pet dander — microscopic skin flakes that cause allergic reactions in sensitive individuals.
The good news is that investing in a good-quality air purifier can help solve at least some of those pesky issues. Some appliances are even designed specifically for pet owners — such as the Oneisall Pet Air Purifier, for example.
Moreover, the Oneisall Pet Air Purifier comes with a washable pre-filter and a handy cleaning brush for a quick removal of excess hair. The best part? It typically costs just $89.99 — cheaper than most other pet-friendly appliances we have tested before.

Looks-wise, the Oneisall Pet Air Purifier does not stray far from the boring industry standard — it is a white rectangular box with a control panel at the top of the unit. It will not win any style awards, but then it does not have to. This appliance was designed primarily to withstand the demands of pet owners, not to be pondered over in your artfully decorated living room. This is where its biggest strength is, even though it may not look like it at first glance. Let us explain.
The Oneisall Pet Air Purifier is a relatively small and light appliance — it measures only 15.47 inches (39 centimeters) in height and 12.2 inches (30 cm) in width, and weighs just 8.81 lbs (4 kg). It is easy to move around the house, but at the same time, its chunky design makes it surprisingly stable and difficult to knock over by accident. We reckon it can easily withstand contact with a curious cat or playful pup.
Moreover, the Oneisall Pet Air Purifier comes with two cat-shaped cut-outs in its air filter covers. This design solution, while not particularly visually appealing (though some may find it quite cute), makes it easy to monitor how much hair and dust have been collected on the air filters. Plus, these cut-outs are small enough to disincentivize any curious paws from investigating what’s behind them and potentially ripping the pre-filter. That is a big plus point for any pet owner out there.
Lastly, the Oneisall Pet Air Purifier is relatively durable. This appliance may be made predominantly of plastic, but it feels thick and surprisingly scratch-resistant. We also found it very easy to clean and dust off.
If there is anything to complain about, then it’s the hinges that keep the air filter covers in place — they feel quite flimsy and delicate. Given that most pet owners will likely take the covers out regularly to clean the filters of hair and other airborne debris, they could be prone to wear-and-tear damage over time. However, it is not something that we would consider a deal-breaker in an air purifier at this budget-friendly price.
Speaking of filters, the replacements are relatively affordable, too. The two-pack costs approximately $32.99 — half what you would typically pay for similar replacements from Levoit and other leading air purifier brands.
Oneisall Pet Air Purifier (PP02): Features
- Auto mode and four manually adjusted fan speeds
- No smart features
- Control buttons can’t be muted
The Oneisall Pet Air Purifier is a relatively simple appliance. It does not have a dedicated app, voice commands or any other smart features, and its air quality measurements are limited to 2.5-micron particles and TVOC (Total Volatile Organic Compounds, gaseous chemicals emitted by many common household products as well as certain natural sources such as animal waste). Notwithstanding, it does have all the essential features that make an air purifier a good fit for an animal-loving household.
Most importantly, the Oneisall Pet Air Purifier has an Auto mode, meaning it can automatically adjust its fan speed to match the levels of air pollution. You can switch it on and leave it to do its job while you go about your day. If you prefer to have more control over the purification settings, the Oneisall Pet Air Purifier also comes with four manually adjusted fan speeds. Moreover, it features a timer and a handy Pet Lock to help keep curious paws from messing with the appliance, as well as an option to dim the lights on the control panel for an undisturbed sleep.
Speaking of the control panel, it is well-marked and relatively easy to use. There is only one issue — the buttons can’t be muted. Every time you want to change the settings on the Oneisall Pet Air Purifier, you will have to put up with some high-pitched beeping. If your pet is sensitive to such noise, this may not be the best option for you.
Oneisall Pet Air Purifier (PP02): Performance
- Catches lots of dust and hair
- Efficient odor removal
- Air quality sensors can be inaccurate
The Oneisall Pet Air Purifier truly impressed us with its day-to-day performance. We had tested plenty of carbon-filtered appliances before, but none seemed to have such powerful odor-busting properties as this one. Within minutes of switching it on, this air purifier made the air in our house smell notably cleaner and fresher. Admittedly, we do not own any pets and can’t say how it would perform when challenged with pungent animal smells, but we are willing to bet it would do a good job of it.
We also liked how quiet this air purifier was. At the lowest fan speed, we could not hear a thing, and we even had to double-check several times that our Oneisall Pet Air Purifier was actually switched on. The highest fan speed is understandably noisier, but not to the point of creating a nuisance. When we measured its noise levels with the Sound Meter decibel-counting app, we did not get a reading higher than 55 decibels (dB). That is equivalent to refrigerator sounds or a quiet conversation.
Moreover, the Oneisall Pet Air Purifier appears exceptionally effective against dust and hair — much more so than you would expect from an appliance of this size. After three weeks of running this air purifier in our bedroom, we took its cover off to assess how much airborne junk it had managed to collect in that time. As you can see in the picture below, the pre-filter was covered top to bottom with debris.
In addition, the Oneisall Pet Air Purifier seemed to be very energy-efficient. According to the brand, this appliance uses about 1 kWh per week — to put that into perspective, most air purifiers of this size tend to use three to five times more — and that checked out with the amount of electricity it used during our testing period. While the Oneisall Pet Air Purifier is not Energy Star-certified, it is not likely to make a huge dent in your utility bills, either.
Let’s move on to the specs now. According to the manufacturer, the Oneisall Pet Air Purifier is best suited for rooms measuring up to 294 square feet (27.3 square meters). While it can be technically used for larger spaces — it is often advertised as suitable for spaces up to 1,400 square feet (130 sq m) — it will take much longer to clean the air in these circumstances, therefore reducing its overall effectiveness.
That is because its Clean Air Delivery Rate (CADR) rating is 188 CFM, which means it does not purify more than 188 cubic feet of air per minute (more about CADR ratings can be found in our guide on how to choose an air purifier) For best results, we would recommend using the Oneisall Pet Air Purifier in medium-sized rooms. That said, we would not look at this spec as a disadvantage. The CADR rating for this appliance is still impressive, and if our at-home tests are anything to go by, also conducive to great air-cleaning performance in general.
To fully assess the capabilities of the Oneisall Pet Air Purifier, we conducted a series of performance tests using a Perfect Prime air particle monitor, a professional device capable of detecting airborne pollutants as small as 0.3 microns. First, we performed an ambient air quality test: We put this air purifier in an enclosed medium-sized room, measured baseline air quality and then ran it on auto mode for 30 minutes. It hoovered up 82.8% of 0.3-micron particles, 90% of particles measuring 2.5 microns and all pollutants larger than 10 microns. Those are some really good results for an air purifier at such an affordable price point.
Next, we challenged the Oneisall Pet Air Purifier to a series of smoke tests. We burned matches and incense sticks to create different types of heavy pollution, then measured the changes in air quality before and after running the air purifier for 30 minutes. We conducted several tests on the maximum fan speed and auto settings, and on average, the Oneisall Pet Air Purifier achieved an 87% reduction in 0.3-micron particles, a 99% reduction in 2.5-micron particles, and a 99.9% decrease in particles measuring 10 microns or more (it is worth noting here that most pet dander particles measure between 2.5 and 10 microns). Again, these results are truly impressive given how affordable it is.
There is only one major downside to the Oneisall Pet Air Purifier — its air quality sensors. These can be slow to react at times, and they do not tend to show accurate levels of air pollution (at least when compared to our Perfect Prime air particle monitor). This did not seem to have a major impact on the overall performance of the air purifier, but if you are keen to keep an eye on air pollution, you may be better off with a different appliance.
Oneisall Pet Air Purifier (PP02): User reviews
At the time of writing this review, the Oneisall Pet Air Purifier was rated a full five stars at the Oneisall U.S. website. Amazon‘s customer reviews, on the other hand, gave it a slightly lower rating of 4.5 out of 5 stars. This air purifier received a lot of positive feedback for its air-cleaning performance, functional design and ease of use. A significant number of testers also praised its ability to reduce unpleasant smells and ease their allergy symptoms.
One user commented, “This air purifier was literally a godsend. For context, my cat ate a string, so he got a few enemas and lots of laxatives. I bought the purifier a few days before this happened, so to my amazement, it came right after the incident. By the incident, I mean, there was poop EVERYWHERE. On EVERY surface. After scrubbing everything twice, my room still smelled strongly of poop. I ended up receiving the air purifier later that day and it did its job. A few hours later, my room smelled clean.”
Negative remarks, though few and far between, tended to revolve around its inaccurate air quality sensors and hard-to-press control buttons. A couple of reviewers also criticised the Oneisall Pet Air Purifier for being too loud on the highest fan speed setting.
One user said, “I wanted to use it for fur specifically, but the highest fan speed (which is made to trap hair) is quite loud. The lowest fan speed is really quiet and not even noticeable, but once you get to stage three and four, it is a loud white background noise. Furthermore, I am not sure how good the air sensor is. It shows a 5, no matter how much my cat blows up his litter box — which is right next to it.”
Should you buy the Oneisall Pet Air Purifier?
The Oneisall Pet Air Purifier is a great no-frills appliance for animal lovers. It may not have dedicated apps, in-depth air quality monitoring or stylish looks, but it does a great job of reducing dust, hair and unpleasant odors, all without making excessive noise or draining your wallet.
✅ Buy it if: You are a cat or dog owner looking for an affordable air purifier for small to medium spaces.
❌ Do not buy it if: You want a smart-enabled air purifier, or need something bigger and more powerful.
If the Oneisall Pet Air Purifier is not for you
Looking for something similar in price, size and functionality? Then you can’t go wrong with the Morento MR5866. Just like the Oneisall Pet Air Purifier, it comes with two air inlets, a compact design and coverage of up to 1,290 square feet (120 square meters). On top of that, it features a dedicated app and can be connected to Amazon Alexa and Google Assistant — and it costs less than $100.
If you are looking for something bigger, consider the Levoit Vital 200S. We are big fans of this appliance — it is exceptionally quiet, smart-enabled and powerful enough to cover spaces of up to 1,900 square feet, plus it comes with a host of pet-friendly features. That said, it also costs twice as much as the Oneisall Pet Air Purifier.
Want something more cat-friendly? How about a table/purifier combo? The SwitchBot Air Purifier Table cleans the air of airborne pollutants while providing a convenient vantage point for your furry friend. That’s not all — it also comes with an essential oil diffuser, mood lights and a built-in wireless phone charger. Great value for less than $200.
Oneisall Pet Air Purifier (PP02): How we tested
We spent three weeks testing the Oneisall Pet Air Purifier. We looked into its design, day-to-day performance, ease of use and value for money, paying particular attention to how it handled hair, dust and lingering odors. We also checked the cost and availability of its replacement filters and measured how loud it was using a Sound Meter decibel-counting app.
Next, we performed a series of air quality tests using a Perfect Prime air particle monitor, an industry-grade device capable of detecting airborne particles as small as 0.3 microns. We started with an ambient air quality test: we placed the Oneisall Pet Air Purifier in an enclosed, aired-out bedroom and ran it on auto mode for 30 minutes, taking air quality measurements every 15 minutes.
Then, we conducted several smoke tests. We burned a handful of matches and incense sticks to expose this air purifier to different types of heavy pollution, then measured the changes in air quality before and after running it for 30 minutes — first on auto mode, then at the highest fan speed setting.
