## Customer Reviews

### ⭐⭐⭐ 







  
  
    Hard to find size! Did the trick! Wish they were individually wrapped.
  

*by C***C on Reviewed in the United States on March 18, 2022*

Received a box of 6 as advertised. The size was perfect for my hard to find filter size. They come in a box with all 6 filters placed inside, BUT not individually wrapped in plastic. Therefore, when storing they are susceptible to dust, and bugs. Hard to store in an area that is clean until use. I wish each filter was wrapped in plastic as they are in the store. Will consider this when repurchasing. I did not want to purchase from Carrier, so bought in bulk. Huge downside lacks individual wrapping. Fast delivery.

### ⭐⭐⭐⭐⭐ 







  
  
    Great filter at a reasonable price!
  

*by G***L on Reviewed in the United States on August 12, 2021*

Really like the construction and materials used for these filters. They may seem a little pricey but I couldn't find any comparable at a better price. Time will tell since I just installed one.

### ⭐⭐⭐⭐ 







  
  
    Reasonable filters
  

*by D***E on Reviewed in the United States on March 3, 2021*

These are just what you would expect. Reasonable filters that are the size indicated. Seem to work fine.
