Color Coded Filters
on October 31, 2026
Posted by: Customer
I love that these filters are colored based on their filtration level so I know exactly which one to reorder. Also the bulk buying discount makes these a must buy. Note that they are packaged in groups of six so once the pack is opened they are all open to the air, so they must be stored to not get dirty or wet while the first ones are being used.

Filters: Quality?
on October 31, 2026
Posted by: Customer
I don't like that they are not individually wrapped. Makes storage more difficult. Packing could have been better. Cardboard on filters damaged/bent. Have not used yet, not time to change.
They don't seem as sturdy as ones previously purchased. Time will tell!

It works fine but it does not fit as tight as the other ones, made by another company, that I have used in the past

I ordered 12 filters and they actually fit well in the vent. I have never before had perfectly fitting filters.

I do not have any mechanism for measuring quality, so I cannot really evaluate the product.
