Buyer's Guide: Choosing the Best Cat Allergy Air Purifier

Several aspects must be considered while selecting the best air purifier for your home. There is no such thing as a universal air purifier that is suitable for everyone.

When comparing filters, consider the kind, size, area cleaned, and replacement filter costs, and then select the one that best meets your needs. Here are a few things to think about while selecting the best one for you.

What Purpose Do Air Purifiers Serve?

Pollutants and allergens are removed from the air by air purifiers. You don’t have to have allergies or own a pet to enjoy the benefits of clean air in your house. However, utilizing an air purifier can significantly reduce cat hair, dander, and odors.

If you are allergic to cats, an air purifier might help you breathe easier when you are near your feline buddy. It will minimize dander and hair in the air before they become irritants.

These things can only be captured by air purifiers when they float in the air. The machine cannot move them once they have settled. Heavy allergens settle rapidly and are difficult to remove.

Room air purifiers can only work in a certain amount of space around them. Moving the air purifier from room to room is required if numerous rooms are to be filtered. You can also order additional units for the rooms where you intend to use them.

How to Make the Most of Your Air Purifier

Consider which rooms you want to utilize an air purifier in. Because people spend the most of their time in these places, bedrooms and living rooms appear to be the most popular selections.

Keep the purifier away from any walls or drapes. Nothing should be in the way of the airflow on all sides of the machine. Using the air purifier where it is most needed can help you get the greatest benefits.

Keep it running to ensure the purest air possible. By turning it off, allergies and particulates can settle. When the air purifier is running, keep the windows and doors to the outside closed. If your machine includes a timer option, you will be able to use it only when you wish, saving energy.

Clear up your filters. The quality of an air purifier is only as good as its filters. They will need to be replaced over time. Typically, such period occurs every 6 months.

Every three months, carbon filters that absorb and neutralize scents in the air should be updated. Learn how to clean your unit’s permanent filters if it has them.

Some of them require vacuuming. Others require cleaning with water and drying completely. Maintaining clean filters not only keeps your air cleaner, but it also extends the life of your air purifier.

Improving Your Home’s Air Quality

In addition to the air purifier, you can take steps to improve the air quality in your house. The air purifier has a limited capacity. You can assist it in reducing its workload by performing the following.

Reduce the number of chemicals you use inside. Paints, insecticides, cleansers, and glues can all contribute to poor indoor air quality. While your air purifier will help, it will not eliminate them from the air if utilized on a regular basis.

Reduce or eliminate indoor smoking, and limit the number of times you burn candles in your home.

On nice days, open your windows to let in fresh air. If you have allergies, use an air conditioner with a filter. This will aid in the circulation of air in your home.

Use your exhaust fans on a regular basis if you have them in your home.

Most importantly, vacuum. You can collect the particles missed by the air purifier by cleaning your floors, furniture, and surfaces in your home.

When these particles are churned up again in the air, whatever you miss has a second chance to be captured by the machine.

Air Purifier Filter Types

Many air purifiers contain many filters. The pre-filter collects big particles in the air, such as cat hair, as they pass past it. The primary filter captures tiny particles and allergens.

For odor management, activated charcoal or carbon filters can be used. Some devices feature all three filters, while others just include the first two.

The American Lung Association recommends HEPA filters, which are high-efficiency particulate air filters. A HEPA filter should be your primary filter. It collects 99.97% of particles larger than 0.3 millionths of a meter.

Odors can be eliminated using activated charcoal or carbon filters. Particles in the air can be removed by your air purifier. However, without an odor-control filter, it won’t do much against odors.

These filters may capture gases and vapors, as well as cooking and litter box aromas. You may assist reduce scents even more by placing the air purifier in the same room as the litter box.

Are Air Purifiers Disturbing?

Air purifiers clean the air by drawing it in via the filtration system and cycling it back out. Internal fans are usually responsible for this. Some can make a humming sound, while others are completely silent.

When deciding where you want to use your unit, choose one that runs silently, even at high speeds, for places like workplaces and bedrooms. When you desire a quieter clean, some machines have a silent option that must be selected.

Advantages of an Air Purifier

Air purifiers may include extra features. This may have an impact on the unit’s price. Some of these characteristics may make using the machine more convenient, while others may not be required.

Indicator of Filter Replacement

A light will show on the machine’s panel to notify you that your filter is nearing or has reached the end of its useful life and must be replaced.

This option may not be necessary if you remember to update your filter based on how frequently you use your computer. However, it can be convenient when you forget to do it.

Maintaining clean filters will keep your machine functioning properly, therefore replacing them on time is critical.

LED Panel Dimming

Adjusting the brightness of the display is useful if your computer lights up while you’re using it in a bedroom. If you’re using the machine in a living or common room, the brightness may not matter in the long run.


When you don’t want to manually turn on and off your machine, you can program it to run for a set length of time every day.

However, if you’re using a portable air purifier that sits on your desk or nightstand, turning it on and off may be so simple that you don’t need a timer.

Remote Management

It’s useful to be able to control your air purifier from across the room. Depending on how frequently you wish to modify the settings, the remote control may be useful.

Intelligent Controls

Some air purifiers may be operated via phone or voice command. While these features are more expensive, they have no effect on the overall performance of the machine.

These are features that cater to the user’s convenience. The presence of Smart capabilities does not imply that the device will perform better than one that does not.
