#4. Winix WAC9500 Ultimate Pet True Hepa Air Cleaner with Plasma Wave Technology: Best Five Stage Filter for Pet Odor and Dander

Winix WAC9500 Ultimate Pet True HEPA Air CleanerMost air purifiers have 2 or 3 stage filters. They do an okay job for some things and fail at others. Some air purifiers move up to four stage filtration and improve on performance dramatically. But, the Winix WAC9500 Ultimate Pet True Hepa Air Cleaners has a five-stage filtration system to knock pet odor, pet hair and pet dander out of your home to the tune of a reduction of 99.99% of all airborne pet hair and dander. The washable advanced odor control carbon filter was specifically designed by Winix with pet odors in mind. The filter can handle smoke, cooking, and other household odors as well.

How the Five-Stage Filtration Works

  1. The first stage is a fully washable pre-filter. That stage traps the largest particles including dog hair and more and holds it there until it is washed away.
  2. The next stage is the True HEPA filter to reduce allergens, pet dander and more.
  3. The third stage is the CleanCel anti-bacterial treated filter to kill germs and bacteria.
  4. The fourth stage is the advanced odor control granular carbon filter which is meant to destroy even the toughest odors in your house.
  5. Finally, air passes through the Winix Plasma Wave technology filter which is meant to attack all pollutants at their molecular level to neutralize viruses, bacteria, remaining odors and VOCs.

The Winix WAC9500 Ultimate Pet True HEPA Air Cleaner was independently tested and found to work well up to 280 sq feet with a CADR of Pollen (194), dust (182) and tobacco smoke (183).

It can be controlled either manually or by remote control with fan speeds ranging from low to turbo. The lights dim automatically during sleep mode. There is a LED filter change indicator light as well.

Recommended or not?

  • Five stage filtration system gets most odors and allergens without a problem.
  • Washable filters can help reduce the number of other filters you are buying.
  • Plasma Wave technology brings peace of mind during cold and flu season.
  • While the unit itself is fairly priced the filters are extremely expensive and very difficult to find.
  • Customer service is not the easiest or most caring to deal with.

#5. InvisiClean Aura Air Purifier: Most Energy Efficient Air Purifier

InvisiClean Aura Air Purifier 4-in-1 True HEPAThe InvisClean Aura Air Purifier has a powerful motor but is still designed to be completely energy efficient. It is able to clean and replace twice the amount of air while still using 82% less energy than similarly sized units. For a room of about 320 sq. ft. the InivisClean Aura Air Purifier has a CADR of 170 CFM (cubic feet per minute). It uses a 4 stage filtration system and features an optional ionizer as well.

Sleep mode runs quietly and without any lights. You can set the unit to run on a timer for 2, 4 or 8 hours or use it continuously for rooms where pets spend most of their time to stay ahead of the pet dander, hair, and odor.

How an Ionizer Works

If you choose to use the ionizer you do so by hitting a button. The ionizer than releases negative ions into the air. These ions will attract small particles to one another forming larger clumps which are then more easily trapped in one of the stages of the air purifier. This air purifier also has a UV-C light that helps to kill bacteria, virus, and mold.

Recommended or not?

Buyer’s Guide to Pet Specific Air Purifiers

When choosing an air purifier for pet related issues like pet dander, hair and odor there are several factors that you have to keep in mind. They are:

  • The CADR
  • The number of filtration stages the purifier uses
  • The suggested room size for the purifier
  • The type of filter the purifier uses


The Clean Air Delivery Rate is one of the most important factors. The higher that this number is the faster the air is being cleaned and replaced. The number is usually given as a numeric value in CFMs or cubic feet per minute. Every unit has a different CADR for different allergens and odors. Pay attention to how well the air purifier handles the toughest odors and allergens (including pet dander) because the others will not be a problem.

The Number of Filtration Stages

In most cases, the higher the number of filtration stages, the better the air purifier will work. If one of these stages is not a True HEPA filter though, it may not really matter. Make sure that you read through the information for the various stages. At least one should be a carbon based filter for odor, a second stage should be the HEPA filter. Look at the numbers for effectiveness ratings as well.

Air purifiers typically have between 2 and 6 stages of filtration with 3 stages being the most common. Some may have additional, optional stages that can be used as needed. These can include UV-C lights (which kill viruses, germs and bacteria) or ionizer units. Ionizers use negative ions to help clear the air by making particles larger and easier to filter out. Both of these however do cause a form of pollution on their own.

Suggested Room Sizes

Any air purifier that you consider will tell you approximately how many square feet it can effectively clean under average conditions. If you know that you are going to be presenting a challenge because you have more than 1 dog or you have dogs that shed all year round, use the suggested room size as a guideline only. For instance if your room is 250 sq. ft. the air purifier that you should consider should handle a minimum of 300 sq. ft to be even minimally effective. It is better to buy the more powerful purifier and then turn it down once it has managed the majority of the pet dander than to make a smaller unit struggle for weeks on end. In the long run, you save energy and eliminate the risk of burning the unit up in the process.

The Types of Filters

There are several types of filters.

  • There are washable filters which are removed, washed and allowed to dry before being put back into place. It is important that you follow the guidelines for washing and drying because a damp filter can allow mold and mildew to grow inside of the unit and defeat the entire purpose.
  • There are also replaceable filters including the HEPA filter, odor filters such as activated charcoal and others, antibacterial treated filters and more.

For a home with pets, HEPA filters and odor control filters are the most important.

What is a HEPA Filter?

HEPA stands for: high efficiency particulate absorber. To meet the government recognized standards for this term, the filter has to absorb and clear the air of 99.97% of all allergens and airborne particles including pet hair, dander, mold spores and others. Some filters have rates at 99.99% while others that may use the term “HEPA-like” will have much lower rates. There are many companies that use the term without actually meeting the standards so always be aware of the difference between a true HEPA filter and one that is not.

Price and Name Recognition

Setting a budget and sticking to it is important especially since there are so many air purifiers that are in the low to mid range that work as well as the higher priced units.
If you are comfortable buying a name you have never heard of, that’s great but some people need to have the name recognition of a known brand. You will probably pay more for the name and not get any other benefits from it.
Make sure that no matter which air purifier you do decide to buy that you can count on the company for service if it is needed and that you will be able to buy filters when it is time to replace them. When doing your research always make sure that you are checking to see if there are complaints about hard to find replacement filters, companies that never respond to their customers or other issues.

Replacement filters should not cost more than the air purifier did and they should always be easy to replace. Most units have a cover in the front or back that swings open and the old filter pops out, the new one slides in with no tools needed.


Pet owners spend billions of dollars on their pets every year. Part of that expense comes from trying to keep up with the dog hair, odors and other issues they bring in to the home. Even the healthiest, most well-groomed dog in the world will occasionally shed a bit and may even end up having a bit of doggy odor as well. An air purifier can help as long as it is chosen and used correctly at all times.
It is important to remember that an air purifier is not magic and it will not clean the room of dog-sized clumps of hair nor will it help with the odor from a sick or poorly trained hound.
Air Purifier for Pets
However, a correctly sized, a multi-stage air purifier will help keep everyone breathing happily and more healthily and may help reduce the risk of allergic reactions from pet dander. Make sure that you look at the most important stats on any air purifier and keep in mind that by design there is going to be some level of noise especially during the early days when it is running at its highest speed. Decide how much noise is tolerable to you, what features that you absolutely need, set a budget and then work from there.

One valuable feature you might consider is the air quality monitor. With this, you know exactly how clean or dirty the air you are breathing really is.

Sleep mode, which turns the fan to the lowest setting and dims the lights for most units is a great suggestion for any air purifier that will be used in the rooms where people are going to be sleeping.

You may find several options that fit your criteria or you may have to make some adjustments to fit your needs and stay in budget. Buy from a trusted seller, opt for higher filtration over other features and never settle for a unit that will only do a fair job if you can get one that will do a good to great one. Remember, clean air is one of the most important aspects of health for everyone in your family.
