  • Ultra Fine Filter Review

    The filter is what I needed. It does an excellent job of keeping dust and allergens from your body.

  • Absolutely the BEST!

    After visiting many sites in search for the right filter I found THE place to buy them. cpapXchange had a great selection and the very filter for which I was searching and, at a GREAT price. I noted that they also had a large selection of cpcp supplies at low and affordable prices too. The shipping time amazed me. My order arrived in 2 days! Talk about FAST! I also couldn't pass up their Mothers Day 'Free Shipping' special. I don't know what their regular shipping would be but I can only hope it is more reasonable than what other places charge. I will be a returning customer to cpapXchange! Thanks to all of you.

    These fine filters trap a LOT of the pollen flyinmg around, when we have our windows open in the spring. Reduces my allergies when sleeping and helps keep my nose from clogging. So glad I found them again here!

  • I recommend this item

    I recommend this item if you wish to prolong the life of your CPAP machine. The foam filter alone if; not cleaned on a weekly basis; will not protect your investment.
