Agree with these reviews, excellent product for those with asthma. I have 2 dogs, and these filters do the job in controlling the hair and dander.

Great features.

This is our second one and I love how it works and all the things it filters out of the air. Also we have 3 big dogs, lots of hair and dander.

Great Filter

I have used these for years. Having pets and allergies, these filters keep dust and dander to a minimum.

Size not accurate.

This item measures 4-3/8", not 4" and will not fit into my furnace. I am very disappointed because I trust this to be a great filter.

reply from Customer Engagement Center

Thank you for taking the time to share your feedback on our Filtrete™ 4" Filter. We sincerely apologize for the frustration you've had with this filter. Because our 4" filters can be used and will offer the same performance in housings that accommodate 5" or thicker filters, our filters are over cut by 3/16''. So, though the nominal width of this filter is 4'', the actual size is 4-3/16''. If you have further questions, you can call us at 800-494-3552 and mention case number 6167574 so we can help. We're available Monday-Friday, 8am-5pm CT and look forward to speaking with you. We've also sent you a direct email with this information. Thanks!

Less dust

Noticeably less dusting needed when using this filter. Also keeps our furnace very clean - said our HVAC serviceman.

good help

We have been having a dust problem, living in an older home. This filter has helped reduce the dust significantly.

For Pet Owners

Use these exclusively; feel they really help lessen breathing problems caused by having two cats and a dog in the house.

Breathing easier

I breathe easier knowing that all the dirt and other microscopic things caught in the filter are not floating around in the air I'm breathing.
