With people everywhere looking to add an extra layer of protection to their homemade, cloth masks, a San Antonio company is offering a viable solution: air filter inserts.

“We’ve heard of people using coffee filters and vacuum bags to put in between their cloth masks,” said David Dilling, president of Filters4Air, which has manufactured HVAC air filters for commercial and residential customers since 1995. “We provide air filter inserts that people can place inside their cloth masks for the extra protection they are looking for.”

The idea for the air filter inserts, Dilling explained, came about when one of the company’s hospital systems customers told him they were buying air filters at Home Depot, pulling out the media, or fabric, off the metal backing and making their own face masks.

“I told them I could find a better way of doing that and give them a better filtration,” he said.

Since then, business has been booming with customers from New York to Alaska placing orders for the MERV ((Minimum Efficiency Reporting Value) 14 filter inserts. The inserts measure 5 inches by 6.75inches, just the right size, Dilling said, to fit into a pocket or the lining of a face mask. Customers can also cut them down to any size they prefer.

“We want to remind people that these are not N95 masks. We’re just trying to improve something for people who have a cloth mask,” Dilling said. “But I do think they are pretty effective.”

Filters4Air sells the filter inserts in packages of 20 for $40 with free shipping anywhere in the country. For large orders, wholesale options are available.

The company manufactures air filters for hospitals, military bases, school districts and HVAC suppliers, among others. In response to the demand for filtered face masks, Dilling is happy that Filters4Air is doing its part of help communities in the fight against the coronavirus.

“We are used to protecting hospitals and military bases from dust, allergens, and other airborne contaminants,” he said. “Now we can help give individuals an upgrade to their cloth masks, just in a smaller, portable size.” delivers air filters to customers’ doorsteps via a subscription service – something that is especially valuable with the need for social distancing and less trips to the stores.

“Our service in San Antonio is contact-less, and we ship nationally as well. We take the stress away from measuring air filters, going to the store and searching shelves,” Dilling said.
