[This review was collected as part of a promotion.] This is just a furnace filter. But it's really good quality and fit perfectly into my furnace cabinet. I'm not sure how I'll be able to know it works well other than waiting for a month or two to pass and understand if it works. I would think if it shows up dirty then it works!

[This review was collected as part of a promotion.] I can't really say this filter works any differently from the Filtrete filters with a lower allergen protection. But I can say I haven't noticed any more dust in the air than with my old filter. It would be pretty hard to tell if there was actually less bacteria in the air. The filter is of good quality though just not sure the extra money for the Allergen Bacteria reducer rely does any more than the ones without that.

The material and shaping of the filters make it look like they would do a great job and filtering out the allergens.

[This review was collected as part of a promotion.] This is a very nice filter screen. Appears to be high quality and has a nice thick feel to it. It is not a cheap flimsy filter like some products. Seems to be doing a nice job in the house as well. It was easy to insert into the furnace too.

[This review was collected as part of a promotion.] I have tried many cheaper brand filters and you get what you pay for. These Filtrete™ Ultra Allergen Bacteria and Virus are worth every dollar you spend on them. These trap so much more dust than any other filter out there. Stick with the best quality when you care about your air quality.

[This review was collected as part of a promotion.] I got these filtrete ultra allergen filter and it works great. It seems to keep the air clean so far and they were very easy to use. So far so good. Will definitely recommend to everyone to go out and purchase for themselves

We started buying the Filtrete 1600 Ultra Allergen because we live in an area that produces lots of pollens, and we have a dog. We can definitely see and feel the difference with using this brand series and other brands. We sneeze less, and there's less dust. Our home has a fresh smell and does not smell dusty like some other places I have been. To make things even better, they are cost efficient. I won't ever change filters as long as these are available.
