filter purchase

The filters arrived in good time. They fit properly. I can't rate their performance as I just started using them. They look to have more filtration capabilities than the ones I have been using.

Best fitting filters

These filters are custom made to your exact size and are top quality. So much better than you can buy in a store, and delivered right to your door are a very reasonable price.
