Best Buy, Target, and Bed, Bath & Beyond sell HEPA filters. Most of these companies also sell products that use HEPA filters, such as vacuums and tower air purifiers.
Best Buy sells HEPA filters on its website but also offers a marketplace where other retailers can sell filters. This allows shoppers to explore alternative dealer options and prices while expanding the number of different types of products available on Best Buy's website. Best Buy also has physical stores that sell these products and can ship products bought online to physical stores for in-person pickup.
Target also sells items online and in store with the option for store pickup for online orders. Filters can be sorted by ratings, which are an average of the reviews given by visitors to the site who have tried out the product, so shoppers get opinions from prior buyers before purchase. The website also features an air purifier buyers guide to help new shoppers learn what to look for in purifiers and filters.
Bed, Bath & Beyond lets shoppers sort by brand, color and cost to quickly find the perfect filter. The site features a find-a-store feature where customers can easily locate a physical store for in-person shopping.
