GOOD QUALITY

Strong material.

I like the 4 pack

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.

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.

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

We've used lower rated Filtrete filters that work well. I bought the Ultra because the others were out of stock. If you buy any Filtrete filters, I recommend changing them before your system shuts down from lack of air flow. They are that good!

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.

Just bought the 14x30x1 merv 12, it is full size, therefore will not fit into wall slot. It should be at least 1/8" smaller all around. Dissappointed, package states it is 13 13/16 x 29 13/16, it is NOT.

Love them. Actualky catch all the fine dust and pollen that has been coming into our home, rather than ruining the AC unit by letting it ruin the coils or blower box.
