Air purifiers can help remove stubborn odors for last-minute cleanups or make sure your home smells fresh to avoid the occasional whiff of unpleasant pet odor.
Choosing the best air purifier can be a challenge, so we’ve put together these reviews. We hope that they’ll help you come to a final decision.

It provides around-the-clock protection with quiet efficiency and low energy requirements.

4. Crane Air Purifier
|Dimensions||25 x 9.25 x 15.3 inches|
|Filter||HEPA, UV-C light|
|Room Size||300 square feet|
Bulky air purifiers might do their job well, but for apartment dwellers, they can get in the way. The Crane Air Purifier is lightweight and compact, so you can tuck it out of the way while it works. Unlike most other designs, the Crane uses two methods to clean the air in your home. UV light kills bacteria and other germs to sanitize the atmosphere, and the HEPA filters capture the surviving pollutants.
Alongside the three-speed settings, this option has a built-in timer and automatic shut-off to reduce energy consumption. The particle filter is also washable, so you don’t have to replace it.
Several users have complained about the noisiness of this device, and it might not be suitable for use in a bedroom while you sleep.
5. Alen BreatheSmart Flex True HEPA Air Purifier
|Dimensions||5 x 15 x 25 inches|
|Room Size||700 square feet|

|Room Size||Up to 540 square feet|
If you have an open-plan household, smells can permeate through the entire building, and it can be difficult to find an air purifier strong enough to handle such a large space. The Blueair Blue Pure 211+ is designed to handle large areas up to 540 square feet, and the built-in carbon filter works to reduce unpleasant odors, including cat urine. Along with the low noise and energy usage, the 211+ uses machine-washable filters to capture 99.9% of germs, bacteria, viruses, and allergens from pollen or your pets.
Several users have expressed concerns about the strong chemical odor emitted when this air purifier is in use. It’s also one of the more expensive options available.

It has several settings available, including a quiet, low setting for late-night operation.
The filters should be replaced at least once every 6 months for the best results. Some users have had issues with the circuitry melting and giving off an electrical burning odor. For safety reasons, this air purifier shouldn’t be run while unattended.

Although this device is meant to run quietly, many users have complained about the hum of the motor when it’s in use. The product also gives off an unpleasant smell when first used due to the new filters. It’s also an expensive option compared to alternative brands.
What to Consider When Buying an Air Purifier
Whether you want an air purifier to get rid of pet-related odors, like cat urine, or to help alleviate allergies, there are a few things to remember before making a purchase. Considering how expensive most air purifiers are, this guide will help you figure out what features you need and how to manage your budget.
Whenever you need to buy something new, expensive or not, it’s important to consider your wallet. When it comes to taking care of yourself and your feline, making sure you can afford to keep food on the table is essential.
While it might be nice to buy one of the top-of-the-line air purifiers with voice activation and all the other technological advancements, they tend to be the most expensive options. If you only need it for reducing the odor surrounding your cat’s litter tray, one of the cheaper options can work just as well. It won’t have the same fancy features, but it’ll be much gentler on your wallet.
Your budget should also consider the cost of the replacement filters. You can purchase air purifiers with washable filters, but more often than not, you’ll need to replace the filters every 6 months or so. After spending a small fortune on the device itself, you’ll want to make sure you can afford the replacement filters along with all your other pet supplies.
Some brands of filters can also be tricky to find. It’ll be easier in the long run if you double-check the type of filters that the air purifier uses before you make a final decision.
Last but not least, the actual filter that the purifier uses is important to consider too. There are three different types, and while they’re often used together, they each have different purposes.
Designed to capture organic matter and volatile organic compounds, activated carbon filters are the best for odors, whether they’re caused by pets or not. For cat urine odors, you want to find an air purifier with a carbon filter for the best results.
HEPA filters are the best for reducing allergies. They work to trap pollutants as small as 0.3 microns, which includes dust, pollen, and pet dander. While they won’t cure your allergies, they can help alleviate some of the symptoms when you’re at home.
Similar to HEPA filters, UV-C light filters can help reduce allergies by capturing pollen and pet dander. That’s not the only thing that these filters are good for, though. UV-C light is the best way to kill bacteria and other harmful germs in your home.
Having a pet means cleaning up smells, stains, hair, vomit, and more...and you can add to your pet clean-up routine with the Hepper Advanced Bio-Enzyme Pet Stain & Odor Eliminator Spray. It's our product, and we love it so much, we just have to share! It permanently removes the very worst smells and stains, and we offer a 100% satisfaction guarantee!

Not all air purifiers clear odors and remove particulates in the air — some do one or the other. To tackle lingering odors, you need to make sure the air purifier that you consider uses the right filters. Activated carbon filters are the best at removing odors, and most purifiers that use these often have HEPA or UV-C light filters to capture pet dander and dust too. So, you often get the best of both worlds, with a clean-smelling house and less pet dander.
Something that many people forget to consider is the space that they have available in their homes. Several of the options on this list are heavy and on the large side. If you’re looking for something portable, those aren’t going to suit your needs.
In the same way, if you only have small rooms in a tiny apartment, buying a device that covers the entire floor will probably be over-the-top. You should buy an air purifier that can cover an area slightly bigger than your living area.
With four replacement filters and several speed settings, including a quiet sleep mode, the LEVOIT True HEPA Core 300 is the overall best air purifier. If you’re short on funds, though, the Beurer LR210 Air Purifier is a budget-friendly solution that still offers many of the same benefits.
Choosing the right air purifier to clear the odors around your kitty’s litter tray can be daunting. We hope that these reviews have made your task a little easier.
