We've been using these for months and have had no issues. They're affordable and work just as well as others we have purchased in the past.

Good quality and priced

Cheap and flimsy feeling but gets the job done! Good price for how many filters you get.

Good filters. Not the best but worth the price they are.

These Filtrete MPR 300 (MERV 5) air filters are my go-to for regular home HVAC maintenance. They strike a great balance between affordability, airflow, and filtration performance. While they’re not designed for capturing ultra-fine allergens, they’re perfect for everyday use—effectively trapping dust, lint, pollen, and pet hair. I use them in a standard residential furnace/AC system, and they’ve helped keep the system running efficiently without straining the blower. They slide in easily and fit snugly. The actual size (15.69x24.69x0.81 in) is accurate, which is important for a tight seal and proper filtration. The three-month lifespan seems accurate for most average households. I usually change them on schedule, and every time I pull one out, it's clear they’re doing their job—plenty of visible dust and debris caught. The 6-pack is convenient and cost-effective, saving me from making repeated trips to the store. If you're looking for a basic, dependable filter to maintain clean air and protect your HVAC system, this is a solid choice. It’s not a high-allergen filter, but for general dust control and system health, it’s excellent.

I use these Filtrete 20x30x1 air filters as part of my Corsi-Rosenthal box setup with a 20-inch box fan on top to help filter out dog and cat dander and hair. In the picture I included, the box is set up between my husky/shepherd mix and my Gordon Setter mix—they shed A LOT. We vacuum this area once a week and change the filters at least once a month, and these filters hold up great. The filters are well-made—they’re pleated, sturdy, and maintain their shape without sagging. There’s no chemical smell, which is nice since they run continuously. They capture pet hair, dander, and everyday dust really effectively. The MERV 5 rating provides solid basic filtration while still allowing good airflow through my DIY box fan system. Overall, they work exactly as I need for my Corsi-Rosenthal box—easy to install, secure fit, reliable filtration, and for the price, you really can’t beat these filters. If you’re building a Corsi-Rosenthal box or just need a solid filter for pet dander and dust, these are a great choice!

I use these filters all the time and they work great for me. They also save me money when purchasing them.

Great product. It is true to size and fit. It is well made

Good quality air filters designed to filter larger particles.

The quality is not good. Outer frame is very weak; made of fat peper. Served for 2 moths only.

I've been using the Filtrete MPR 300 filters for a while now, and they've consistently performed well in maintaining the air quality in my home. The 16x25x1 size fits perfectly in my HVAC system, and the 6-pack offers great value. These filters effectively capture household dust and lint, thanks to their electrostatically charged fibers. I appreciate that they don't overly restrict airflow, which helps my system run efficiently. I make it a point to replace them every 90 days, as recommended, to ensure optimal performance. Pros: Effective at trapping dust and lint Affordable 6-pack offers good value Doesn't impede airflow Cons: Not designed for capturing smaller particles like pollen or pet dander Overall, the Filtrete MPR 300 filters are a solid choice for basic air filtration needs. If you don't have specific concerns like allergies or pets, these filters should serve you well.
