    HVAC filter
  

*by R***H on Reviewed in the United States on January 22, 2023*

I never knew until looking on Amazon that K&N made HVAC filters what an amazing product works great been using it for about 3 months now ease of cleaning the best part reusable never have to replace it just keep it clean Well worth the investment

### ⭐⭐⭐⭐⭐ 







  
  
    Wish I bought it sooner!
  

*by A***R on Reviewed in the United States on January 12, 2023*

Very easy to install and looks like great quality. I’ve only had it in for a week and it’s collected quite a bit of pet hair and dust already. It will pay for itself in 3 months. The cost for 4 air filters is around $45, so it will definitely help me save $.

### ⭐⭐⭐⭐⭐ 







  
  
    Perfect
  

*by C***M on Reviewed in the United States on January 4, 2023*

I’ve tried several washable filters and none would fit the return air grill except the K&N.  Perfect fit.  I used cardboard filters for a while and when I would replaced them, they were always bent out of shape and allowing unfiltered air to enter the system.  Great product.
