These filters fit my high efficiency furnace perfectly putting an end to my struggles with the cheap filters I was buying at the home improvement stores.

I change my furnace filter

I change my furnace filter every three months. I have allergies and I want my air as clean as possible. My HVAC guy has warned me about using too high of a MERV value due to the potential of restricting airflow which has the potential to damage the system. I like that these have the feature of not restricting airflow. Very easy to use.

The filter is excellent. I wish the size was a little bit more on target.

Great filters! They work well and we love the automatic delivery. We have several dogs in our house and no other filter has worked this good.

I have used your filters for years. I started when I purchased a new Air conditioner for my house. In the last few times I've used them they now make a loud vibration sound. I went from merv 13 to 11 now I'm thinking I should go down to 8. I don't want to I like that they take so much out of the air. Did you change something :thinking:.
