    CXC Notes: Hello, we're sorry to hear that this product did not work out for you. On the product page we do list that the dimensions for this filter is approximately 3.5 inches long by 1.5 inches wide. We also list each machine that is compatible with these filters. We hope this helps. Sleep well.

  • I kind of thought when they referred to the filter as a “pack” there were at least two filters in each pack, apparently a pack is only one!

    Should advertise that a pack is one item!

  • 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.
