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.

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!

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 using different kinds of filters. After using these Ultra Allergen filters for a year, I just received another order. Why? Because they work. The air is cleaner and less dust on furniture. It's a big deal to be able to breathe.

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 have made a big difference in the amount of dust we get on our furniture. Plus the price for 4 is what you would pay for only 2 at most other stores.

We shopped around buying filters from different stores, buying filters online through subscriptions. Not only are they more expensive the Quality is not the same. With a membership We get 4 filters for the price of 1.

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.

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

I own an older home. My HVAC air return is an odd size. Can never find it at other retailers. Its always in stock online and at a better price with Sam's. I place my order and 2 or 3 days later the box is delivered to my front door! No shipping charges since I'm a plus member!
