Anyone who has had a cat in their home for very long knows the experience of having cat litter dust floating through their house. There is also the pet hair and dander to deal with, and all of these can cause sneezing fits and other allergic reactions.

You don’t even have to have allergies to be bothered by these airborne annoyances. They can affect anyone, and you may want to do something about them.

Sometimes, changing out the litter isn’t always an option, and that won’t do anything for the cat hair and dander that are still floating through the air. The most comprehensive solution to the problem of having too many particles in the air is to get an effective air purifier.

What to Know before You Buy

  • The purifier needs to be big enough– According to, the larger the room, the larger the air purifier will need to be. If it isn’t big enough, then it isn’t going to effectively filter out particles in the air.
  • Consider getting a low dust litter- While you may still want to buy an air purifier for your house, you may help the situation by using cat litter that is dust free or low dust. You will still have other particles to contend with in your air, but this can make the purifier’s job easier.
  • Check the warranty– Buying an air purifier can be quite the investment, and you want to make sure it will last you for a decent amount of time. To that end, you should check the warranty and ensure that it is good for at least a year. You may also want to go for the longer warranty to provide greater protection.
  • Consider your and your cat’s allergies– As suggests, your allergies may play a role in how severe the dust problem is for you. Don’t forget about your cat’s allergies as well. You may need special types of filters to deal with these issues and make the air more breathable.
