Filtrete 20x20x1, AC Furnace Air Filter, MPR 1200, Allergen Defense Odor Reduction, 2-Pack (exact dimensions 19.69 x 19.69 x 0.81)

This is a very good filter, but after one month of use, I dont notice a difference compared to the Filtrete 1900 filter. Since I purchased my house in May 2015, cigarette smoke seepage from neighbors has been a daily and nightly problem. In addition to expensive ventilation renovations (all duct work replaced, baseboard sealant after installation of energy recovery ventilation [ERV] system to correct low airflow, Whispure air purifier running 24/7), I tried 3 types of filters at the return. The first was a washable filter that was convenient but mostly only caught dust bunnies. The Filtrete 1900 performed better for smoke and dust (esp. noticeable on my textured ceilings) and was labeled for smoke filtration. This charcoal version is a good concept, but without a noticeably better effect and because other customers mentioned that charcoal residue might fall into ducts, Im not sure if Ill purchase it again. The charcoal version is about $5 cheaper per filter than the Filtrete 1900, which is a plus. Ill probably alternate between the charcoal and 1900 filters in the future since they each have advantages.

Good

Good package. Easy to unpack and install.

Does pull odor out of an apartment. They are really very messy though as charcoal drops out of the filter each time you pick it up and move it. They are rather expensive for what they are in my opinion.

Perfect. Thank you!

Great filter for animal owners

Helped take odor out of house

Worked great. Expensive but worth it.

Made the air smell great.. Wish they were cheaper tho.

They are air filters, they filter the air as advertised. Not so sure about any odor control as the carbon is sprinkled on discharge side like pixie dust. IMO like expecting the same type of coating with large granules of sugar to make the air sweet.
