Buyer’s Guide: Selecting the Best Air Purifier for Cat Litter
These days, you can find air purifiers with all kinds of features, and it’s easy to get lost in all the details. Staying focused on several key features can help you stay on track and find the best fit for you. Here are some important things to keep in mind when shopping for a new air purifier for cat litter.
Reducing odors is usually a priority for cat litter box issues, but not all air purifiers perform equally when it comes to odor control. So, make sure that the air purifier that you select has a filter that is specifically designed to trap odors. Most air purifiers that are designed for homes with pets have features that help with pet odor control.
Air purifiers of varying sizes and fan speeds will have different room coverage capacities. So, if your cat’s litter box is in a smaller room, like a bathroom, then a smaller air purifier with less room coverage will suffice. There’s really no need to purchase an air purifier with a room coverage that greatly exceeds your room’s square footage. So, you can end up saving on costs by choosing an air purifier that’s appropriately sized for the room you plan to place it in.
Along with budgeting for initial costs, it’s important to consider how much you’ll spend on replacement filters. Replacement filters usually have to be changed between 3–12 months. The frequency will depend on the quality of the filter as well as your room’s air quality. So, make sure to check an air purifier’s filter prices and lifespan before purchasing an air purifier. It’s possible to save on costs in the long run if you purchase high-quality filter replacements that are designed to last longer.
Out of our reviews, the LEVOIT Core Pet Care True HEPA Air Purifier is the best air purifier for cat litter because of its versatile multi-filter system and relative affordability. The Dirt Devil Air Purifier is an excellent budget option that has a straightforward design and consistent delivery. If you’re looking for a powerful air filter with many helpful features, the Alen BreatheSmart 45i Air Purifier is worth the investment.
Choosing the right air purifier can help immensely with maintaining your cat’s litter box. It’ll also ensure that your house is free of odors and common airborne allergens.
