Air Purifier Buyer’s Guide

There’s no doubt that you love your pets, but even the biggest dog or cat owner needs a great pet air cleaner to remove pollutants and unwanted smells from inside the home. Additionally, family members or friends who visit your home will also appreciate an air purifier, which can remove pet dander from the air. Pet dander is what causes an allergic reaction in people with pet allergies. These allergies can be mild to severe and can cause reactions that include itching, hives, watery eyes, and in severe cases, difficulty breathing.

But how can you find an air purifier that’s powerful enough to remove all of the pet dander and other pollutants from the air? Not all air purifiers are created equal. Some are designed only for very small spaces, such as a bedroom, while others can cover hundreds of square feet in the home.

If you’ve never owned an air purifier before, then you may not know even where to begin in terms of finding a new air purifier that will work specifically for your household.

That’s where we come in.

Below you’ll find a list of important features to look for that can easily determine an air purifier’s value and overall quality.

Air Purifiers for Pet Dander Allergies

If you or someone in the home is allergic to dogs or cats, then you’ll need to be extra careful when choosing a new air purifier for the home. Only air purifiers that are equipped with a true HEPA filter can effectively remove irritants and pollutants from the air. Removing a significant amount of pet dander from the air can help to reduce symptoms associated with allergies and can even cut down on the severity of allergic reactions.

So, what is pet dander exactly? Pet dander consists of tiny particles of your pet’s skin. The dander can get trapped in furniture, bedding, curtains, carpet, and can float in the air, traveling throughout the home.

Your pet’s fur usually won’t be the cause of an allergic reaction, however, it does contain a high content of pet dander. Because of this, pet hair can be a big problem if you don’t vacuum often and your pet is a heavy shedder. Pet hair can also trap feces, urine, and saliva. To make matters worse, if you have a lot of pet hair around the home, you’re also feeding the dust mite population, allowing the mites to thrive and multiply. Dust mites are also responsible for producing more allergy substances that can travel through the air.

Keep in mind, pet dander is the biggest problem here. Once dander makes it into the air, it can float all over the home and may remain floating in the air, for several hours. Despite the fact that pet dander is a microscopic particle it can still get trapped in an air purifier’s filter.

How HEPA Filters Works

How HEPA Filters Works

The HEPA filter is designed to remove up to ninety-nine percent of pollutants from the air. In fact, they can trap particles that measure in at just 0.30 micrometers. An air purifier that’s equipped with a true HEPA filter can efficiently cut down on the amount of dust mites, dust, pet dander, and other harmful pollutants in the home.

UV Light Technology

Do UV air purifiers work? Yes and no. UV-B light can trap and kill mold spores, bacteria, and viruses, but without the help of a powerful traditional filter system, these air purifiers will not trap larger particles including pet hair and pet dander, making them a poor choice for people with pets.

The Addition of the Ionizer

These days, most new models of air purifiers now come equipped with an ionizer feature. This can be in addition to a model with a HEPA filter, or it can be the sole function. An ionizing purifier isn’t able to remove pet dander from the air, but they do work to help trap larger particles such as dust. When turned on, an ionizer emits a positive and negative charge. Voltage is applied to the ionizer’s built-in needles, resulting in the creation of electrons. These electrons are discharged into the air where they can attach to air molecules, forming negatively charged ions. These ions are then dispersed throughout the room where they can attach to pollutants such as smoke, pollen, and dust. This allows the air pollutants to easily become trapped in the air purifier’s filter. Or the particles will fall to the floor where they can be vacuumed up.

Most ionizers aren’t able to remove larger particles from the air, such as pet dander, so they’re not the best choice for owners of pets. However, traditional air purifiers with an ionizing feature that can be switched on and off, can offer extra air purifying power compared to a standard air cleaner equipped with just a true HEPA filter.

Air Purifiers that Can Handle Pet Dander

If you’re a dog or cat owner who suffers from a severe allergic reaction, or you have asthma, there are filtration based purifiers on the market that are specifically designed to control and reduce the amount of dander in the air. That being said, the best air cleaner for pets should be one that features a variety of control methods designed specifically for people with pet allergies.

You should look for a model that is not only equipped with a filtration system designed to trap larger particles but one that also features other types of technology that’s specifically designed to trap bacteria and smaller particles in the air.

Air purifiers with PECO, also known as photoelectrochemical oxidation, are able to capture smaller particles, pet dander, and any other types of pollutants in the air.

Narrowing Down Your Choices

If you’re not sure what type of air purifier you need, learning about the different features available can help you to narrow down your choices. Consider whether you need an air purifier with a shut-off timer, air quality sensor technology, filter life indicators, UV-B light, or smartphone compatibility.

Typically, models equipped with these extra features will come with a higher price tag, but often, the steeper price is worth every penny.


UV light is added in order to kill the bacteria that tends to accumulate on the filters of air purifiers, but as we mentioned earlier, this feature works best when combined with a true HEPA filter.

Activated Carbon

Many top of the line air purifiers come equipped with an activated carbon filter which works to trap pet odors, gasses, and chemicals. These filters are often combined with potassium iodide or zeolite in order to improve the filter’s toxin removal power.

Pre-filter Action

A pre-filter is a removable air filter that’s designed to capture larger particles including dust, skin flakes, hair, and other large particles. This extra layer of filter protection also works to extend the life of the air purifier’s main system. Most types of pre-filters are also washable, so you won’t have to worry about replacing them once every one to six months.

Replacing the Filter

Replacing the Filter

On average, most filters must be replaced every six months. If you can’t remember to change the filter or how long you’ve had the new filter, then a model with a filter life indicator can really come in handy. These come in the form of an indicator light or a digital display that will show you how much filter life is left.

Programmable Timer

Built-in timers are a great feature if you don’t want your air purifier running around the clock. Models with this feature will automatically shut off after one-six hours, depending on the setting.

Do I Need an Air Purifier?

Surprisingly, most people don’t know just how polluted the air inside their home is. Considering you spend most of your time indoors, constant exposure to everyday contaminants can lead to health issues later down the line.

But before you run out and buy the latest air purifier, it’s important that you ask yourself the following questions:

  • How many rooms in your home do you want the air purifier to reach?
  • What type of filter do you need?
  • Where will the air purifier be placed?
  • Do I really need an air cleaner?


When you’re shopping around for an air purifier, consider why you need one. Obviously, if you have allergies, then you’ll want to go with a model that’s equipped with a top of the line HEPA filter. These filters are considered the most effective option, especially considering they can trap pollen, ragweed, mold spores, and pet dander.

Pet Odor

Owners know that their homes smell like their pets. Usually, this goes with the territory, but with the right air purifier, you can totally prevent your home from smelling like dog. These air purifiers contain added chemical and pet odor filtration, in addition to a HEPA filter.

Air Purifier Size

The size of the air purifier you choose should also be a factor. When we say size, we don’t mean the size of the unit itself, but the amount of square footage the purifier is able to handle. So, before you buy, consider the square footage of your home and how much space you want the unit to purify. To precisely sum it up, measure the width and length of the room or rooms in feet, then multiply the length and width together. This number will tell you how much space the air purifier should reach, ideally. You can easily find out how much space a model can purify by reading the spec sheet.

Air Change Per Hour

This is a spec people with pet allergies should pay close attention to. Air change per hour refers to the number of times a unit can filter all of the air in a room per hour. Most high-end models are able to purify the air three to four times an hour. An air purifier with a high air change per hour rating is perfect for people with animals or cat allergies. If you’re looking online for a new air purifier, look for the words room size for air change per hour. This number should be matched with your square foot coverage needs.

You can also use the model’s cubic feet of air processed per minute in order to calculate the square footage the air purifier much reach in order to accomplish four air changes each hour.

Is The Air Purifier Tough Enough for Your Home?

How efficiently an air purifier removes contaminants from the air ultimately depends on the overall quality of the purifier. Top of the line models are able to remove just over ninety-nine percent of contaminants, while lower priced models will usually only remove twenty to forty percent of contaminants.

Does Style Matter?

These days, most air purifiers feature a sleeker, more modern look. However, there are still those large, bulky models out there that can end up being a real eyesore. Fortunately, you can easily find an air purifier in our top five list that will work with both your budget and the existing décor in your home.

Air Purifier Placement

Most manufacturers will recommend placing the air purifier in the bedroom because this is where people typically spend most of their time. Keep in mind that most air purifiers are designed to purify just one room. Because of this, you may need to consider purchasing an extra purifier or two for the other rooms in your home.

Care Needs

Many top of the line air purifiers don’t require much maintenance. However, if you’ve purchased a model with a disposable filter, then you must replace the filter according to the manufacturer’s recommendations. Doing so will ensure that the filter is able to continue functioning properly and remove high levels of pollutants from the air. Failing to replace the filter often can majorly impact the air purifier’s efficiency.

  • Most HEPA filters must be replaced every six to twelve months.
  • Carbon filters must be replaced every three to six months
  • If your air purifier has a pre-filter, these should be replaced once every three to six months.

If you don’t want to have to worry about replacing the filter or filters, then models that use ultraviolet light or heat to eliminate allergens, kill germs, and purify the air don’t require filter replacement and can be a great option for some homes.
