The Winix HR900 Ultimate is a replacement of the ever popular and familiar Winix 9500. It can purify up to 300 sq. ft., and delivers stable airflow spreading across the 4 fan speed. Of course being an air purifier, it does come with features that are enough to rival its competitions in the market. It has true high-efficiency particulate air (HEPA) filtration made out of fine mesh that can capture 99.97 percent of airborne pollutants, including pet dander, pollen, tobacco smoke and any allergen that is as small as 0.3 microns.

The washable advanced odor control (AOCTM) carbon filter makes sure that the Winix HR900 can also capture pet, kitchen, and household odors, as well as smoke that can also give your household an unclean impression. This additional washable filter can also extend the life of your HEPA filter. Like with other air purifiers with washable filters, you’re spared with costly filter replacements that only add up in the running costs. 

Furthermore, the clean air delivery rate (CADR) of the Winix HR900 is also way ahead of the Winix 9500. Dust CADR is at 200 cubic feet per minute, pollen CADR at 220 cubic feet per minute, while the smoke CADR reaches 194 cubic feet per minute. 

The filtration system of the Winix HR900 consists of many stages. The air goes through the add-on Ultimate pre-filter, and the standard washable pre-filter. It will pass through the AOC Advanced Granular Carbon Filter which will then capture the smoke and pet odors, as well as extend the life of the HEPA filter. The process ends with Winix’s own PlasmaWave technology which will break apart allergens and any microscopic level debris at molecular level. If you are on a budget then you can consider Winix 5500-2 which is comparatively cheaper.

Pet Air Purifier Buying Guide

How Pet Hair and Pet Dander Can Become a Nuisance

How Pet Hair and Pet Dander Can Become a Nuisance

When your pets scratch their body, it releases hairs and dander in the air, which if breathed in, may cause allergies to some people. Pet dander, for example, may cause upper and lower respiratory tract symptoms. This includes congestion, sneezing, runny nose, tight chest, wheezing, sometimes itching, watery eyes, or, eczema and rashes. 

Aside from pet hairs, and pet dander, urine stains can also leave bad odors that stings on your nose. These urine stains can release ammonia in the air which can trigger respiratory problems, especially for people that are suffering from asthma and bronchitis. 

Pet hair, pet dander, and urine smell is very hard to effectively filter out from the air. So if you don’t have a specialized air purifier that is designed for this job, not only does it fail to purify the air you are breathing, but also damage the device itself in the long run.  If you are a pet owner, it is advisable to always make sure that your pet and family is away from these dangers. In this case, a specialized spot cleaner, or air purifier should be considered.

In this part, we will help you choose the best specialized air purifier for your pets and your family. 

Factors to consider when buying the best air purifier for pets

1. Maximum area coverage

When you are considering purchasing an air purifier, you should always look first for the maximum area coverage of each device. Depending on how large the room you plan to put an air purifier on, an air purifier should be able to cover each area to get the best possible result. 

In the list we have covered above, for example, the Alen BreatheSmart 45i offers the best maximum area coverage. It will be able to cover up to 800 sq. ft., while other air purifiers in the list can only reach up to 200 sq. ft. maximum area which is good enough. If you specifically want a an air cleaner that covers a bigger square footage, you might need a large room air purifier instead. 

2. Type of Particle filter

Each air purifier contains a filter that will be able to capture pollutants at microscopic level. However, effectiveness of the filtration depends on what type of filter the air purifier has. If the primary concern is all about pet hair, and pet dander, options like true HEPA filters will be able to capture fine air pollutants down to 0.3 microns. 

This is because, to meet the HEPA standard, a filter must remove at least 99.97% or more of particles that are as small as 0.3 microns in diameter. In perspective, the size of human hair is approximately 80 to 100 microns in diameter. That is how small a HEPA filter should be able to capture. 

Beware of air purifiers with HEPA-type and HEPA-like filters as these are not true HEPA. They will not be able to remove 99.97% of particles that are 0.3 microns in diameter, and is only used as a term to confuse consumers to  buy low-quality air purifiers. However, if your concern is not about allergen, and just some larger than 0.3 microns dust particles in the air, these options will work just fine too. But don’t expect it to release a fine purified air as with the true HEPA.

3. Activated Carbon Filter

If you are looking for air cleaners that will be able to remove air pollutants and particles like smoke, volatile organic compounds (VOCs), smoke, and odor, then you should look for an air purifier that has activated carbon filters. 

Carbon filtration works by adsorbing all the impurities in the air, and trapping them on the surface area of the filter infused with activated carbon. Note that the adsorption process is different from absorption. Absorption is the process wherein the fluid is dissolved by a liquid or a solid, while adsorption is when the atoms, ions, or molecules from a substance only adheres to the surface of the adsorbent. We’ve a very detailed post on the working of activated carbon filters that could further clear things up for you. 

4. Recurring Cost

Air purifiers are known as an expensive investment, and expenses never end even after purchasing. To make sure that the air purifier works efficiently and effectively as it was first bought, you should also be ready to spend money on filter replacement. However, there are some air purifiers that come with a washable filter (usually odor filters) that you can just wash and are ready to use again as it is. If recurring cost is a big issue for you, look for air purifiers that come with a washable filter. This will help you in keeping the running cost in check.

5. Warranty

Finally, warranty is also a big factor in purchasing air purifiers. As you can tell, air purifiers are an expensive home investment. With that said, you expect to get the most out of your money with the device by using it for a long period of time. 

If you are purchasing an air purifier, also look for how long the manufacturer will be able to provide free service to your device. In this list, for example, the highest number of warranty goes on for three long years. That is three years of manufacturer support should you have any problems with your air purifier within the time range. 


Air purifiers are an expensive investment. So if you want to spend money on it, you wanna make sure that the one you are getting is of your money’s worth. If you really want an air purifier with a quality air filtration system, you should get the one that offers true HEPA, like all the air purifiers we put on this list. 

Beware of anything that says HEPA-type or HEPA-like, as these terms are mostly used to fool consumers into buying an air purifier, expecting that it will work the same way as a true HEPA when it is not.

A true HEPA air purifier is a must-have for pet lovers who are dealing with pet hairs, dander, and odor all the time. If you are one of those people, any devices we put on this list will be able to give that.
