FAQ
Most residential filters need replacing every 1-3 months depending on usage, pets, and air quality. Check your filter monthly—if it looks clogged or dirty, it’s time for a new one.
MERV 8 works well for most homes and handles common dust and pollen. If you have allergies or pets, consider MERV 11 or 13. Check your HVAC manual first, as some systems aren’t designed for high-MERV filters.
The size is printed on the frame of your current filter, usually something like 16x25x1. Measure the actual dimensions if the marking is worn off—filters are sized in inches (length x width x thickness).
Higher ratings can restrict airflow in older systems not designed for them. This makes your HVAC work harder and can lead to problems. Stick with the manufacturer’s recommendations unless you’ve confirmed your system can handle denser filters.
Fiberglass filters are thinner, less expensive, and catch larger particles. Pleated filters have more surface area, last longer, and trap smaller particles including allergens and mold spores.
Yes, True Blue filters are guaranteed to be free from manufacturing defects. Contact customer service if you receive a damaged or defective filter.

Clients Thought
Customers appreciate that True Blue filters fit properly and do what they’re supposed to without costing a fortune. Many mention cleaner air in their homes and fewer issues with their heating and cooling systems since switching over.

I’ve been using True Blue filters for about two years now, and they’ve made a real difference in my home—the air feels fresher and I’m not sneezing as much with two dogs around. They fit my furnace perfectly and the price is reasonable, especially when I order a 6-pack.

After my HVAC guy recommended changing filters more often, I switched to True Blue and haven’t looked back. They’re affordable enough that I don’t mind replacing them every month during heavy-use seasons, and my energy bills have actually gone down a bit since my system isn’t working as hard.

I run a small property management company and use True Blue filters in all rental units. They’re reliable, easy to stock in bulk, and tenants never complain about fit issues when they change them themselves.
