Breathe Naturally3 Pack Replacement Carbon Filter - Extra Thick Carbon Pre-filters, Measured Exactly to Fit Fellowes CF-300PH/AP-300PH Series Air Purifiers - Premium Air Quality & Odor Control

These filters are used in a Fellowes fan I use every night in my bedroom when I sleep. The noise helps me sleep but I have a dust allergy problem which requires I avoid the re-circulation of dust while I circulate the air. This filter, along with it's associated HEPA filter do a great job of keeping the dust out of the air.I've used this fan now for several years with complete success.

Many times I have ordered this product but other sellers have bent the product and I had to send it back. Other sellers sent a generic brand even though I ordered the Fellowes brand. I am happy to report that this seller sent the appropriate product and took great care in sending it to me. Very grateful.

Fellowes Carbon Filters work great, however, they should not be folded for shipment. It makes them difficult to put in the machine.

Arrived quickly & fits easily into the unit. These are replaced every 3 months so not sure why the pack contains 3 instead of 4. However if you are like me, you will use 2 & realize you didn't order another pack so having a 3rd gives you enough time to get it done.

The air in my house is replete with dust and unseen allergens. This filter really makes a difference.

These filters are much better than the other filters I have ordered. They are thicker and more sturdy than the off brands of this filter. I would recommend to my friends..Beware of cheap filters, you will get what you pay for.

If air filter changed with both filters, heap and carbon , the air filter works beautifully !

We purchased this filter before and the quality is not the same anymore. It's so thin and it's see through....You can see the side by side comparison, the old filter is much thicker. This will be returned.
