Good product

Great product

Does not fit 24" X 24" opening. It is 24 1/16 inches instead of 24"X 24"

Excellent and very quiet! Bought several different sizes recently and they are much better than those from HD (quieter and well built).

The "new" style has more pleats, restricts furnace airflow, and shuts down the furnace after 2 minutes.

Filter is too large and doesn't fit. Restricts airflow and it sounds like a jet airplane. Will be returning these.

Great air filter at almost half price from other retailers. The air becomes so fresh at my 3 bedroom home after I replace our old filter with this filter. Highly recommended 3M, which brings the quality.

I have lots of allergies and have a few room air filters throughout the house. Instead of purchasing the very expensive Hepa filters / charcoal filters, I use these instead and they do a great job. Much less expensive.

[This review was collected as part of a promotion.] Perfect size filter. Perfect for bacteria and virus filtering. This is perfect for all seasons. Great quality filter. Very durable and easy to install. I highly recommend this fliter.

I wanted to like these, but the size it states is too big for the opening. I don't understand how that is happening, considering I bought the correct size.
