How to Choose the Best Air Purifier for Cat Allergies?

CatHow to choose the best air purifier for cat allergies is a common question for me and all other cat-lovers. I love my cats so much. They are so cute but some of my friends and family members do not. They feel unwell when they come to my house and play with my cats. Some of my friends and family members with cat allergies will cough, sneeze, or have a stuffy nose and red eyes.

According to a study on Allergy, the official Journal of European Academy of Allergy and Clinical Immunology, 26 % of Europeans and 12% of Americans are allergic to cats respectively. The syndrome ranges from mild respiratory problems to a life-threatening syndrome called anaphylaxis. Therefore, an air purifier to remove allergens from cats is so important to protect people with cats allergies.

In fact, from a general perspective, the air we breathe is very important and can go a long way in determining the condition of our overall health either at present or in the future. Issues such as airborne allergies, cigarette smoke, dust, smoke wildfires, or even air pollution caused by industrial activities, etc. are usually caused by circumstances beyond our control likewise allergies caused by pets around us, particularly cats.

Therefore, the best we can do is to consider how to effectively manage the situation with the use of an air purifier. It now leads to the all-important question for all cat-lovers: “How to choose the best air purifier for cat allergies?”.

Factors to Consider When Choosing the Best Air Purifier for Cats Allergies

Cat AllergiesRegardless of how much we love our cats or other pets like dogs, they can adversely affect the quality of the air we breathe in our homes. There would always be challenges like unpleasant smells from accidental droppings on the carpet and odors emanating from the litter box as well as pet hair and dander that often tend to circulate is enough to trigger allergic reactions in some people.

However, some of the best air purifiers for cat allergies come in handy in such situations.

Granted that it can be quite confusing when trying to choose the most suitable air purifier, considering that a good number of them are backed by awards, charts, and certifications that “prove” they’re the best, I recommend that you sift through the data and consider the following factors as shown below:

  • Make sure the model you want to buy is appropriate for the size of the room where you want to keep it. Some air purifiers for pets range in capacity from 140 to 1560 square feet.
  • Virtually every air purifier for pets will make use of some form of filter, you should seek HEPA filters for optimal results.
  • You should also consider other factors like the affordability of filter replacements (i.e. if you’re cash strapped and want to reduce recurring expenses). Note that some filters are permanent in nature and can be vacuumed. Some others have pre-filter that can be washed and reused (these ones will be ideal if pet hair is a challenge since they can trap fairly large particles.)
  • Compare their CADR rating which is an indicator of how a particular air purifier would filter certain pollutants. The higher the CADR rating, the higher efficiency
  • Check the respective product spec of each brand and take note of their noise levels indicated in decibels. Some air purifiers are noisy while others are noiseless, so depending on where you’re going to place it, you may want to go for a quieter device.

Now we are done with the basics, it is time to learn other necessary details about some of the best air purifiers for cat allergies, produced by top-rated brands such as Coway, Levoit, and GermGuardian, as well as the pros and cons associated with each of them.
