“We’ve been working with Filterbuy for over a year, and it’s been a great experience. They are knowledgeable, friendly, and they always have our unique sizes in stock. We’ve purchased a variety of filters, and each one was delivered promptly with no issues. Our Filterbuy account manager is also fantastic. Plus, the air quality in the office is much better than with our old filters. We highly recommend them!”

Why should we do business with you?

We built our business from the ground up with efficiency in mind. We have invested heavily in our technological infrastructure to provide you the quickest, seamless, most cost effective solution to buying air filtration products on the planet. We allow you to minimize your inventory cost by shipping most orders within 24 hours (and for the majority of our products we offer a 3 day guarantee). Most other companies are a minimum of a two-week lead-time, often times even longer in reality. We also are the direct manufacturer of the vast majority of products that we sell. There are no other middlemen involved. Did we mention that we make ordering our products as easy as clicking a couple of buttons? You and your employees will save countless hours in back and forth phone calls. You place an order on our site and your order, big or small, arrives as promised. Quick and seamless.

Why air filtration – isn’t it just a commodity product?

The vast majority of the products that we sell are relatively low dollar value but take up a lot of space. The warehouse space necessary to stock a meaningful amount of filtration products can get expensive quickly (whether outright or opportunity cost) and transportation is one of the biggest portions of the product cost. What this boils down to is that every time a product that goes to an end user is touched or stored for a meaningful amount of time, the cost of the end product goes up meaningfully. We are offering you direct, just in time access to the largest selection of filtration products on the planet, direct from the manufacturer. Our efficiency savings allow us to pass these savings to you, our customer. Did we mention that we are a technology and logistics company at our core? Our operating infrastructure is unparalleled within the filtration industry.

Where are your products manufactured?

The products at the core of our business are 100% made in the USA, components and all, by an American workforce. If we ever stock a third party OEM product (which we do to service our customers from time to time) we will clearly state the origin of that product so that you and your customers can take that into account when making a buying decision.

What selection of filtration products do you offer?

Our selection is unparalleled, and constantly growing. We aim to be both the first and last stop for all of your air filtration products, whether for typical residential use or heavy-duty industrial needs. If you have a specific need that we are not currently servicing, we would love to work with you to see how we can help. We are filtration experts and can almost always work with you to provide the service that you need.

What is your mission?

We believe in giving back to both our Country and society as a whole. Too many companies have lost sight of their overall purpose, and quite frankly, use excuses to move manufacturing to lower cost destinations. Our products are made 100% here in the USA, primarily by a disabled workforce. Through a partnership with the Alabama Institute for the Deaf and Blind (AIDB), we have contracted to pay a fair market wage to a disabled workforce that would otherwise be without a job. When you buy our products, you are directly contributing to the employment of an American workforce that would otherwise not have an opportunity to work and would otherwise rely solely on Government assistance. We will be sharing more about our mission in the days and months to come.
