Review on 🌬️ Whirlpool 8171434K Air Purifier Active Carbon Pre-Filters - 4-Pack (Large) - Fit AP51030K, AP45030K, APR45130L, WP500 - 18x16.5 inch by Ramon Hood

I have three indoor cats and have had three hot tub air purifiers installed throughout my home for a number of years. These filters are easy to install and do a great job of capturing dust and cat hair. As every cat owner knows, we sometimes find little tufts of fur under the sofa or between pieces of furniture. Since the use of these air purifiers, such finds are rarer. As this is a review of the filters themselves I will say that they are slightly better than the regular filters I have tried in the sense that the filters are usually replaced every 50-60 days rather than every 30-40 days . These filters are a little more expensive, but because they're a little denser, I feel like they trap more dirt.
