Excellent product along with the GermGuardian. I am still a smoker and disabled so I am in the home 90% of the time and also have a medium size dog. After using the GermGuardian almost a year now, I found that so much of the dust produced by "every day living" let alone the smoke has been reduced substantially. I can tell by how much is on the filter and what's NOT on everything else. Easy to install and of course easy to order on Amazon. Highly recommend for those with allergies, infants/young children, elderly, those that live in cities, etc., and for any household. I use one in my master bedroom (fairly good size) and in the living room. Less "film" or "dust bunnies", etc.

I was very pleased with the filters. When it's time to replace my filters I have a harder time breathing. I just replaced the filters with the GermGuardian FLT525OPT Genuine True Hepa Filters. The air is fresher and I got immediate relief! I have a dog and cat and the GermGuarian make such a difference. Thank you!

Love these air cleaners. I have 3 in areas of the house from moldy smells to cat litter odors. Works great! Keep the filters clean. Not cheep but worth it.

Works great

My machines will need filter fellas after the wildfires are out. I'm glad I have these on hand ready to change!

This air purifier works GREAT and removing odors quickly from the air.... it does do what is say it will :)))We also like the timer feature, so we can select up to 8 hours run time and then the unit shuts off on it own.Great value for the money ! I highly recommend this product.

Took a week to get after ordering (even with Prime) but the filter swap is simple and straightforward. The filter / purifier system works great.

Every July I replace the filter. Have never had a problem. Use the HEPA nightly. \
