Where to buy a radon test kit or monitor

PRO-LAB names Lowe's among the stores that carry its radon test kits, which include the PRO-LAB RA100 short-term kit and the PRO-LAB RL116 long-term kit. RadonAway's retail page names Lowe's among the outlets for a limited line of its products, without saying which; none of the other makers we cover names Lowe's for a radon product in text we could check. Many Lowe's searches are for radon fans and mitigation kits rather than tests; those are covered below.

PRO-LAB names The Home Depot among the stores that carry its radon test kits. RadonAway's retail page names Home Depot among the outlets for a limited line of its products, without saying which; we found no other maker we cover naming The Home Depot for a radon product in text we could check. If you buy any kit in a store, PRO-LAB's advice applies to its own kits too: if you cannot find them, call PRO-LAB to buy directly.

The Home Depot's own site has a Radon Detectors department, in its Electrical department, and a search of its site for radon fans lists inline radon fans and radon mitigation fan kits. That says the store sells these kinds of product online; it does not say which models a given store has on its shelves. A fan is one part of a mitigation system; see radon fans and mitigation kits below.

PRO-LAB names Menards and Ace Hardware, along with True Value and other hardware chains, among the stores that carry its kits. It also names the supermarket and pharmacy chains Kroger, Fred Meyer, Giant Eagle and CVS. RadonAway's retail page names Menards among the outlets for a limited line of its products, without saying which; we found no other maker we cover naming these stores for a radon product in text we could check.

First Alert names Walmart, along with Amazon and others, among the retailers for its products. That is a statement about First Alert products in general, not about its RD1 radon test kit in particular, so check the listing before you buy. We found no other maker we cover naming Walmart for a radon product in text we could check.

Several makers point buyers to Amazon themselves. Ecosense says the EcoQube can be bought from its website or on Amazon in the US and Canada, Airthings says its Wave Radon can be found on Amazon and in selected retailers, First Alert names Amazon among its retailers, and Detekt's page for its radon kit says it is also available on Amazon. For the products below, we have matched an Amazon listing to the product we cover; each product's card and page link to it, with the affiliate disclosure beside the link.

Most monitor makers sell on their own sites: Airthings on its US store, Ecosense on its website, and X-Sense on its US store. Laboratories that analyze kits sell them directly too. Alpha Energy Laboratories, now part of Eurofins, sells short-term, long-term and radon in water kits, and Radon.com sells short-term, long-term and radon in water tests. Buying from the lab means the kit goes back to the same lab, and both sites let you register a kit and check a result; see radon test kit results. PRO-LAB sells its RA400 short-term kit, with the lab analysis included, on its own online store.

Lab fee

The charge for analyzing a mail-in kit. Some kits include it: First Alert, Kidde, Detekt and empowerDX say theirs do, except New Jersey's state fee; PRO-LAB labels its RA400 and RL416 kits Lab Analysis Included; and RadonAway says its Air Chek kit includes the analysis and USPS return shipping. PRO-LAB lists its RA100 and RL116 apart from those kits, and has you send any required fee with the RA100's detectors.

Before buying, check what your state offers. The EPA says some states offer free or discounted test kits, and that kits are also available from some local or state American Lung Associations. Kansas State University's National Radon Program Services sells kits online and by phone at 1-800-767-7236: its short-term kits go back to Alpha Energy Laboratories in Texas and its long-term kits to Radonova in Illinois, with analysis included. It notes that its short-term kits must reach the lab within 10 days of the end of the test.

2. 2Step 2 of 3:

   Or order from Kansas State

   Online or by phone at 1-800-767-7236; results for its short-term kits are at Alpha Energy's site.

   Or borrow a monitor

   Some libraries and Extension offices lend digital monitors; see borrowing or renting a radon detector.

Many store searches are for radon fans and mitigation kits. Fantech's where-to-buy page asks for a zip code or city to find a nearby distributor, and RadonAway sells on its own site and links a page on where to purchase its products. RadonAway's retail page names Lowe's, Home Depot, Menards and Amazon as outlets for a limited line of its products, and says non-professional installation of a radon fan or system is not meant to take the place of installation by a qualified radon professional. Fantech's manual recommends installation by a trained, licensed, certified mitigation professional, and says checking radon levels after installation is required.
