Review on Signature Cleaning Replacement Filters - The Ultimate Solution for Cleaner Spaces by Kimberly Polcher

I bought this item to avoid backorders. They work great as expected and I like to have spares on hand. I use compressed air to clean them and reuse them for a few months before throwing them away. I find them cheaper by the dozen. No complaints, we order as needed. I recommend to my friends. I believe this is the best way to buy.
