About Our Products
At A1 Filter Service, we specialize in custom-sized, reusable HVAC filter kits designed to make home air filter replacement simple, affordable, and effective. Each kit includes a durable metal frame built to last, along with 12 high-quality polyester filter inserts — enough for a full year of clean air.
Our filters are easy to use: just slide in a new insert each month. No more guessing sizes or buying disposable filters every few weeks. Because our frames are made to order, please allow up to 2 weeks for delivery.
Clean air, less waste, and long-term savings — that’s the A1 difference
