Price Considerations

When I started comparing prices, I noticed that Merv 11 filters are available at various price points. While it can be tempting to go for the cheapest option, I learned that investing in a higher-quality filter pays off in the long run. I usually compare brands and read reviews to ensure I’m getting good value for my money without compromising on performance.
