Buying Guide: How to choose the right Air Purifier

While you are looking to buy the best air purifier for cat allergies, there are a few other factors you need to consider before making the final decision. Besides ensuring that your air purifier is good at capturing cat hair and pet smell; your room size, filter, filter replacement, and noise levels also contribute to finding the perfect air purifier for cat dander and smell.


Different air purifiers for cat hair and litter smell come with filters affecting their performance. Nowadays, most air filters have HEPA filters that are best for collecting particles as small as 0.3 microns to keep the air in your house clean and contaminant-free. Some purifiers have the H11 HEPA filter, while others use the H13. 

The HEPA filters help remove particles from the air and carbon filters eliminate the odor. Some air purifier models do not contain carbon filters and only remove dander and hair. If you want to have a smell-free room, choose one that has a carbon filter. Besides HEPA and carbon filters, some air purifiers also have a pre-filter that helps remove larger particles.

Filter Replacement

When you decide on buying an air purifier, it is important to keep in mind that the filters need regular cleaning and replacement. Some HEPA filters are not replaceable, and some need replacement after 12 months. You may also need to remove old carbon filters and insert new ones after 3 to 6 months. Filters for purifiers range between $20 and $200, depending on the model. Choose an air purifier model with readily available filters that do not cost a lot compared to the unit.

Room size

The next thing you need to consider is the size of the room you need the purifier for. If you have a small bedroom but a huge living area, you will need a different model for each room, according to the size of the room. There are numerous models for catering to specific room sizes like 129ft2, 183ft2, 310ft2, 547ft2, 840ft2, 1252ft2, etc. Air purifiers for larger rooms also work well for smaller rooms at low speeds throughout the day. 


Air purifiers are lifesavers as they improve the air quality in the room. Yet, sometimes while reducing air pollution, they may contribute to noise pollution. When looking for an air purifier for cat hair, do not miss checking the decibels of sound that the device produces. Most purifiers come with multiple operational ranges that have different sound levels as low as 20dB for some models. This Noise Decibel table shows what sound you can relate to the decibels mentioned in the box.

DecibelCorresponding sound
0Hearing threshold
20Rustling leaves
40Light  rainfall
