According to statistics, around 68% of households in the US have a pet, with 90 million dogs in those households. That’s a lot of dog hair to deal with and many of those dog owners also suffer from allergies. One of the best ways to keep your home clean of dog hair and to prevent allergic reactions is to get an air purifier. In this article, we will review five of the best air purifiers for dog hair available on the market.

Benefits of Air Purifiers

The main reason for getting an air purifier for dog hair is to prevent allergies, asthma and other respiratory issues. According to WebMD, around 30% of adults and 40% of children in the US have allergies. Additionally, one in five people have either allergy or asthma-related symptoms.

These statistics how prevalent these problems are and dog owners are especially vulnerable to flare-ups due to dog hair, dander and odors. Common symptoms of allergies include sneezing, runny nose, congestion, difficulty breathing and watery, itchy eyes.

However, preventing allergies is not the only benefit of having an air purifier. As a dog owner, it will give you fresh air and filter any bad odors. A good air purifier will also keep your home cleaner, which means that you won’t have to clean as often as you do now.

Air Purification Technologies

All of the benefits that come with air purifiers are a result of different air purification technologies. Let’s take a closer look at a few different options that are used in high-quality air purifiers.


High-Efficiency Particulate Air, or HEPA, is the most common air purification technology used in all air filtration products. The main reason is because it is the one of the most effective methods in trapping airborne particles.


Although HEPA filters are very effective, they can’t get all of the contaminants out of the air. For this reason, many air purifiers on the market combine several purifying technologies. These units are called multi-stage air purifiers and they often include activated carbon filters.

Activated carbon is great at removing volatile organic compounds, gases and odors from the air. These filters use a process called activation to change the structure of the carbon by heating it or with a chemical process. This makes carbon filter air purifiers more efficient than just HEPA brands.


Although ultraviolet (UV) radiation is rarely used as a purifying technology, it is sometimes included as an option in some multi-stage air purifiers. This technology uses a type of UV wavelength (UV-C) to destroy particles and not just trap them as mechanical filters do.

The downside lies in the fact that this type of radiation can be harmful to humans. That’s why only a handful of air purifiers use this technology and they do it in a very efficient manner.


This purifying technology uses physics instead of standard filters. There are metal plates with a negative electronic charge included in the air purifier, which is creating an attraction between particles and the plates.

These “filters” don’t have to be replaced like HEPA filters. Instead, you only have to clean them regularly and they’ll be as good as new.


The last air filter method is ozone purifying technology. Ozone has similar particle-destroying properties as UV-C technology. However, it can also lead to various health issues when humans get overexposed to it.

If you decided to go with an air purifier that uses ozone, you must use it properly and follow the manufacturer’s instructions or you may risk your health.

Tips on Using Air Purifiers for Dog Hair

Air purifiers can be very effective in reducing dog hair, dander and odors but they may not be as effective if you don’t use them properly. Here are a few tips that will help you in getting the most out of your air purifier.

Find the Right Place

You can’t just stick the air purifier in the corner and expect to see great results. While you may do this do keep it out of the way, it won’t be as efficient as it would if you find the right place for it.

For example, most air purifiers maximize their air purifying power if they have at least 18-24 inches of clearance on all sides. It is best to place the air purifier close to the center of the room or in a spot where your dog often spends his time. This way, the purifier will pick up and clean most of the particles before they scatter to other parts of your home.

Keep the Outward Air Flow Free of Obstructions

Similar to the last point, you don’t want to obstruct or block the outward flow of clean air. If there is an obstruction to this path, the fresh air will constantly recycle on itself without getting spread across the room.

If the air filters out of the top of the unit, don’t put your air purifier under a table or something else. In some units, the air comes out on the side or on the front, in which case you shouldn’t block those pathways.

Keep the Air Purifier On

For an air purifier to operate at peak performance, it is necessary to keep it running 24/7. This device is not like a cooling fan that you can turn on and off as you need it. Most models are extremely energy efficient, so there is no need to be worried about it running up your electric bill.

Keep Doors and Windows Closed

While it’s not possible to keep windows and doors closed at all times, it is important to keep them closed as much as possible to give your air purifier a chance to clean the air inside the room over and over again.

When your doors or windows are open, the clean air can escape and outdoor pollutants can flow right in, making it harder for your air purifier to keep the air free of contamination.

Change the Filter As Often As You Can

Regular filter changes are necessary because an air purifier is only as good as the filter is. If his filters are dirty and clogged, the unit will not operate effectively.

Most air purifiers for dog hair come with a filter change light. This light indicates when you should change the filter as the manufacturer outlines in the user manual.

How to Choose the Best Air Purifier for Dog Hair

Now that you know how an air purifier can help you with dog hair, allergens and odors, let’s take a look at some of the most important features to consider when you shop for an air purifier.

Coverage Area

The size of an area that an air purifier can keep clean effectively is called the coverage area and it is probably the most important factor you need to consider. How big the coverage area you need will depend on the size of your room. 

If you are not sure what coverage area you need, you can take measurements to determine it. First, measure the length (L) of the room, and then measure the width (W). After this, multiply the two numbers to get the total area of the room. Choose an air purifier that has a coverage area that slightly surpasses the area of the room.

Particle Removal Efficiency

In addition to the coverage area, there are a couple more factors you should consider before buying an air purifier. These factors are particle removal capacity and clean air delivery rate (CADR).

Particle removal capacity shows how effective an air purifier is in removing particles of certain size. For example, most HEPA filters remove 99.7% of particles as small as 0.3 microns, which is extremely efficient.

Meanwhile, CADR measures the overall capacity of the unit and describes how much air it can process in terms of cubic feet per minute (CFM). Look for the higher ratings when you consider CADR – that means that the unit can clear more air over a certain period of time.

Filtration Type

We’ve already mentioned what air purification techniques exist – now it’s time for you to choose between units with a different number of stages and filtration techniques.

Today, most air purifiers are multi-stage but they can have a different number of stages and each of them can combine different purification techniques.

Filtration Life

Most air purifiers come with filters that have consumable elements in them, which means that they need to be replaced regularly. How long will the filter last depends on a few factors, especially on the amount of use and the type of filter.

In general, HEPA filters are changed every 2-3 years, while filters with an activated carbon element can last up to 3 to 5 years. As we already mentioned, some air purifiers have permanent filters, like ionic systems that only need to be cleaned regularly. There are also some HEPA filters can also be washed and used indefinitely.

However, most manufacturers will recommend filter changes and suggest an interval after which you should change your filter. This is based on “regular use”, so it may not be suitable for everyone. If you feel like you are using your model frequently, it is perfectly fine to change filters more often.

Ease of Use and Portability

Although most household air purifiers are designed to be portable and easy to use, some are just more convenient than others. 

We suggest choosing units that can easily be picked up and moved to another area. Also, go with those models that are simple to use and don’t require any advanced tech knowledge to operate.

Noise Levels

Compared to air conditioners or box fans, air purifiers are not that loud. However, they do emit some noise. The level of noise is determined by the size of the fan and the overall design of the air purifier.

That being said, most air purifiers produce noise in the range around 50 decibels, which is quieter than the sound of the regular conversation. However, some people find a soft background noise soothing and helpful for falling asleep.
