Why do litter boxes smell?

Quite often you might wonder, why your litter boxes smell. Even after thoroughly cleaning them, the smell still lingers around. Some smells are so strong they even spread through your entire house. Well, you are not the only one facing this problem and it is more common than you might think. We are going to share with you some of the reasons as to why this might be happening. After which, we shall also share with you some remedies and how air purifiers can help with litter box odors. We hope you can later be able to identify the best air purifier for litter box smell.

  • Since cats eat meat on daily, their stool will smell really bad. This is because of the high animal protein content found in meat.
  • Another cause of smelly litter boxes is pet urine. Since urine especially cat urine is quite concentrated, it will leave a very strong unwanted smell.
  • No matter how hard we try, we can never be perfect. That’s why even if you remove poop every single time your pet takes a dump, you will still leave some poop particles behind. These particles will eventually accumulate and collectively leave a bad lingering smell.
  • Cats will usually claw through the litter as they prepare to bury their poop. This act will also leave the boxes scratched. Some of these scratches will even be a bit deep. Over time, these scratches become hide outs for bacteria that eventually produce bad odor. Ensure to change the litter boxes about once each year
  • Lastly, you probably might not be cleaning your cat's litter box. Yes, we said it. Some people actually believe that because the pet buries its poop in the litter the poop won’t smell. Therefore this buildup of cat secretion leads to a very smelly experience.

How can I prevent litter box from smelling?

It’s not all doom and gloom actually. There are still very many ways you can combat smelly litter boxes. Like;

  • You should try cleaning the litter boxes at least twice a day.
  • You should also empty out and thoroughly wash litter boxes frequently. This should be at least once every month.
  • The litter boxes you have should be replaced at least once or twice in a year.
  • Consider using a litter deodorizer. Make sure it does not irritate your pet otherwise it will start taking its poop sessions out of the litter box.
  • The good old fresh air solution. So, try putting the litter boxes in an open location with lots of fresh air.
  • You should also consider using activated carbon bags. You can place the activated carbon bags under the litter. The carbon bags will gradually absorb the bad odor.
  • Changing the contents of your litter could also help. You will need to look for litter that doesn’t absorb the bad odor and that is also easy to clean like the world’s best cat litter clumping formula.

Do air purifiers help with litter box smell?

Air purifiers eliminate litter box odor or pet odor mainly through absorption. Let us explain this a bit more. The main component of an air purifier that helps with smells is the carbon Filter. The carbon filter works by capturing, trapping and absorbing odor causing particles found in the air. So a more sophisticated and advanced the carbon filter will definitely perform extremely well at odor elimination. Though, overtime the carbon filter will start to fill up and get clogged. Therefore, you will have to keep replacing it each time it gets clogged which is usually between 3 – 6 months.

Factors to consider when looking for an air purifier for litter box odor

  • Activated carbon filter: This is the heart of any purifier’s odor elimination capabilities. The carbon filter is designed to handle all types of gasses and volatile organic compounds including ammonia that originates from the poop and urine that makes our litter boxes smell. Having a washable carbon filter is a plus. Because it means you will save on having to frequently buy replacements for the carbon filter.
  • A Filter replacement indicator is also important. It will notify you when any of your filters needs replacement so that you can quickly know when its time to replace your filters.
  • You should also consider the noise level of the air purifier:  This is because if the air purifier is noisy and you place it near your litter box, your pets might find it annoying and could decide to poop elsewhere.
  • Room size is another important factor to consider. You should always ensure the air purifier can  cover the entire room its put in. This will also help in advising where you can or rather should place your air purifier. Therefore, before you get your air purifier, you should have an idea of how big your room is so as to make sure that the air purifier you choose can cover the entire room.
  • The air purifier room coverage also determines the location of the litter box. If the air purifier has poor room coverage it will have to be placed closer to the litter box.
  • Portability of the air purifier:  The air purifier should be portable enough so that you can easily move it around for maximum and efficient use.
  • Stages of filtration: Ideally you would need a purifier with at least 3 stages of filtration. This is because even though we are after getting rid of litter box smells and bad odor, we still need to keep the air clean. This air could contain litter dust, pet dander and much more even if it smells great.
