Are Air Filters 20x20x1 Safe for Home Use?

When it comes to air quality, it's essential to make sure that the air entering your home is clean and free of contaminants.

Food-grade air filters

are an excellent way to keep the air in your kitchen pure and prevent any issues from occurring throughout the house. The American Society of Heating, Cooling, and Air Conditioning Engineers (ASHRAE) has established a standardized system that all air filter manufacturers use. It's important for customers to be aware of the two most common signs that their filter is nearing the end of its life.

The Nordic Pure MERV 12 air filter is a popular choice, but there are other options available that offer similar performance. Many customers have given positive reviews for these filters, and they come in a wide range of sizes. Plus, they are likely to be available at a local hardware store if you need them quickly. If customers keep delaying replacing their filters, they will only increase their energy bills, so it's time to invest in a new one.

MERV 8 air filters are almost as affordable as the least efficient products, so they offer good value for money. When deciding between a MERV 8 and MERV 11 air filter, it's important to remember that using an air filter with a rating that is too high can be just as bad as using one that is too low. This is because it can cause airflow to stop, which isn't ideal for any air system. If smoke-filled air is finding its way around the clogged filter instead of through it, then it's time to install a new one.

These filters are designed to trap microbial contaminants such as mold, bacteria, and viruses, as well as allergens that can cause mild to serious health effects. If you can't find the Nordic Pure for your size or if you need a new filter right away, Honeywell FPR 9 filters and Filtrete MPR 1500 filters are similar options that are widely available at retail stores. Food-grade filters also offer safety and savings if they are replaced regularly. Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in a home without affecting airflow.

Meanwhile, air filters with a MERV 14 rating or higher are designed for commercial air conditioning systems that can withstand coarser filter material. It's essential to remember that food-safe air filters should be changed in a timely manner in order to prevent dust, debris, or bacteria from entering the kitchen.
