It is a good filter, but I’ve been told now by three different air-conditioning companies that they are too hard on your air condition unit and it makes them work too hard and to go to a lower grade.

This filter is restricting airflow. Our return air is so loud when our gas furnace is running. Also we hear a thump a few seconds after the furnace kicks off. Not sure what the deal is.

These filters are the best I have used. They get pet hair, dirt and dust although I have cats and dogs so I actually change my filter every month but it does cut down the dusting

These are the best filters I have ever purchased. They cut dust to a minimum making house cleaning for me so much easier. And such a great value for an average of $10 each. I replace them every 2 months.

Great price when compared to Lowes contractor 4 pack, I have been using the 1600 filtrates for years. I have 2 Fur babies so i change the filter every 2 months. AC service guy says the inside of my ac is very clean so they are doing a great job

I have tried cheaper brands but I always come back to filtrete. They have different merv ratings for different situations. I have Saint Bernards and lots of dog hair and dander and it takes care of it all.yes they are expensive but worth every penny.

I appreciate the price Sam’s club provides us for this air filter. It’s almost half priced as compared with the other retailer. The 3M quality is always the best. I can immediately feel fresher air in my home after replacing the old filter with this one. I bought 12 packs with this price, enough for next 3 years. I highly recommend this product to everyone.

When I saw these on sale at Sam's, I immediately went down to stock up. They clean the most miniscule particles of dust, debris, and other particles from you recycled air, and add years of life to you HVAC unit by preventing this particulate from getting caught up in your coils.

Rating is not based on scientific analysis but based on observation and long-term use. The 1600 MPR appears to substantially reduce as claimed pollen, pet dander, smoke, bacteria and viruses. The latter two elements cannot really be determined. Changed every 2-3 months and the amount of collected debris in the filter is supported of filtering.

My friend recommended these filters and I'm very happy using them. The air is a lot cleaner; I don't have to change the filter out for 3 months. I highly recommend, although pricey, it is definitely worth the money. Also, they have a reminder when to change out filters.
