Best Air Purifiers for Pet Owners : Best Air Purifier for Pets

Even though we may be allergic to pets, not everyone can afford a hypoallergenic breed dog. Your cat or dog may also be allergic to pet dander.

They may also bring in dirt and germs from the street if they spend time outside.

A quick wipe down of their paws with water can be helpful, but if you want to make sure your house is clean and your pet’s allergies are under control, you can use an air purifier Brachycephalic. An air purifier will help you breathe as cleanly as possible.

If you are sensitive to environmental pollutants, have allergies or have concerns about your breathing, an air purifier can be a great purchase.

You can find many different air purifiers, both portable and installed at your home.

The best air purifiers are those that can remove the smallest particles from the air.

Air purifiers don’t always work. To reduce the amount of air contaminants, allergens such as mold must be removed.

Your room requirements and preferences will determine the air purifier that is right for you. Here are some options for air purifiers that might be suitable for you.

What are we considering for air purifiers

It doesn’t have to be difficult to buy an air purifier. However, it is important to understand what’s available and what you should measure before buying.

We began by asking a few questions about prices, clinical studies, brands, and other market factors.

Questions to Consider

These are some questions you should ask before buying an air purifier.

  • Do you want to purify your entire house, or just one room?
  • Which pollutants would you prefer to filter?
  • How big is the space where the purifier will be installed?
  • Are you willing to clean or replace filters?
  • How big, loud, and what programming features do you want for your air purifiers?

When shopping for an air purifier, make sure it has the right capacity to fit the space in which you will be using it.

The majority of models will indicate the recommended room size. It can range from 150 to 1,000 square feet.

Also, you’ll need to decide if additional features are required, such as odor control, sleep mode or air quality indicator light.

You should also pay attention to the noise level of the machine when it is on. While some air purifiers emit white noise or pink noise to help you sleep, others are quite loud.

We have compiled a list of the top air purifiers for pet owner.

Three different angles for white air purifier


Promising review: I bought this purifier hoping that it would reduce allergy symptoms caused by pollen and dust. This little air purifier is amazing.

It instantly reduced my symptoms. The light also tells you when the filter is getting more dust. (When the dog runs past or an outside door opens, the light turns yellow or orange). It’s good for charging and the battery life is great. It runs on low and auto all day, and it lasts for 7-8 hours.

It has been used in my car and at home. Although it seems impossible to believe that this small unit can create a bubble of air around you, it works. The manual states that the filter will last for 6 months. It’s extremely quiet and only gets slightly more loud when filtering more particles. It is not enough to feel any breeze. –JZ

What should you look for in an air purifier


There are some air purifiers that are more powerful than others. The size of your room, the number of pets and any allergies you have will all impact the power required.

To ensure that your needs are met, make sure you check the coverage area.

Expert Buying Tip

“Filters can also be marked with a Clean Air Delivery Rate (CADR), which indicates the amount of airflow through the filter.

Make sure you match the CADR (clean-air delivery rate) of the filter with the space where it will be used.

–Dr. Payel Gupta is President of the New York Allergy and Asthma Society


Some air purifiers have additional features such as temperature control and odor control.

If the filter is going to be visible, you might also consider its appearance. You can find one that matches your decor in a range of colors.


Some people love the white noise of traditional air purifiers. Others are more annoyed. There are many machines that are extremely quiet and others that let you adjust the volume.

Some models allow you to set up runs that operate at different volumes and times of the day.

  • What is the working principle of an air purifier?

Air purifiers can be used in any of the three methods, but some use all three.

    • HEPA (high-efficiency particulate aero) filter: These mechanical pleated filters force air through a fine mesh to remove pet hair, pollen, bacteria and other airborne particles. HEPA filters are the best.
    • Activated carbon filters: These filters absorb odors from the air and remove them.
    • UV filters: These are made with ultraviolet light to kill bacteria and germs. These filters are often used in conjunction to HEPA filters.
  • Do air purifiers reduce pet dander?

An air purifier that has a HEPA filter will remove pet dander. It filters out particles as small as 0.33 microns.

HEPA filters can be used to remove pet dander from the air.

  • Are air purifiers able to remove hair from cats and dogs?

HEPA filters are a great option if you have pet hair in your home. Pet hair can lodge on clothing, carpets, sofas, and bedding more often than you think. You might still be interested in pet hair removal products.

  • Is there a better place to store your air purifier?

The more air purifiers are located near the pollutant source, the better they work. Keep your pet’s purifier close to their bed or crate. Do you have a cat? To help eliminate unpleasant odors, place the cat’s litter box near it.

  • How can you maintain an air purifier

Follow the instructions on your air purifier’s owner’s manual. Some filters can be washed with soap or water.

Some air purifiers can be replaced every few months.

You may see a light on your air purifier to indicate when it is time to change the filter. If it does not, you should keep an eye on it for three months.

How do I choose an air purifier

Permanent vs. Mobile

Think about what you need from your air purifier. Are you looking for cleaner air in your whole house or just one room?

There are many sizes and types of portable air filters.

Permanent air purifiers are usually part of your home heating ventilation and air condition (HVAC), and need to be replaced regularly.

Remember that permanent air purifiers work only when the HVAC is on, so they may not be able to run outside if it is too cold.

An HVAC system that filters the air in mild weather may cause an increase in utility bills.

Types and methods of filtration

There are many different types of air purifiers that you can buy, each of which filters different types and sizes of particles.

Remember that pet hair is much larger than pollen, dust and smoke particles. If you are primarily concerned about dander, your air filtering needs might be lower.

Here’s a general rule of thumb:

  • Pollen and pet hair are made up of larger particles.
  • Dust is a medium-sized particle.
  • Consider smoke a very small particle.

For allergens such as smoke, pollen, and dander, it is best to search for HEPA filters (high-efficiency particulate aerator) for portable and permanent air purifiers.

This filter captures large, medium and small particles in the air.

Carbon filters target gases. These filters can be used to filter smoke and other contaminants from the air.

Many air purifiers have both HEPA and carbon filters.

Know the dimensions of your room before you buy a portable purifier. The purifiers can only be effective in a certain space. Make sure you carefully read the package to ensure that the purifier is appropriate for your room.

Multiplying the room’s width and length will give you the square footage.


What does the CADR rating of air filters indicate?

Clean air delivery rate (CADR) is the measurement of portable air filters. This rating indicates the size of the particles in the filter and the space where it can be used.

To effectively clean the air, larger rooms require higher CADR ratings.

If your room measures 200 square feet, you will need a CADR rating of 130. For a room measuring 500 square feet, you should get a rating of 325.

What is the MERV rating of HVAC air filters?

The MERV (minimum efficiency reporting values) of HVACs that filter air are used to measure their effectiveness.

No matter what particles you are trying to filter, filters should be 10 or more on this scale. The MERVs range from 1 to 20. For purification to be effective, filters must be replaced regularly.

Safety Tips

Some air purifiers can be harmful to your health. A unit or filter that isn’t regularly maintained or cleaned will not work well.

Consider that air purifiers can emit ozone which can cause irritation to your lungs. These include plasma, uncoated UV lights that are not coated properly, or ionizers.

You should also ensure that your home is free from pollutants by using other methods.

  • Do not allow people to smoke inside.
  • Clean and vacuum regularly.
  • If possible, ventilate with outdoor air.

The bottom

An air purifier can be used to reduce particles and other pollutants in your air. You can purchase many portable air purifiers.

Models that are less expensive tend to be smaller in size, while larger units may work in more rooms. However, they will likely cover your entire home.

A professional is recommended if you are interested in installing an air purifier into your HVAC unit.
