Dust Free

What Dust Free does

Dust Free, founded in 1982 and headquartered in Royse City, Texas, manufactures indoor air quality (IAQ) equipment for residential and commercial HVAC systems. The company is operated as a product brand under RectorSeal, which is itself a subsidiary of CSW Industrials, and runs the brand out of RectorSeal's headquarters at 2601 Spenwick Drive, Houston, Texas. Dust Free's product portfolio is organized under its "IAQ3" strategy, which integrates three layers of air treatment: MERV-rated and electrostatic filtration (including the MERV 16 "Sixteen" and Bypass HEPA air cleaners, MAC media air cleaners, and the Dust Fighter and EnviroGreen filter lines), carbon-based purification (Active Gold carbon fiber ionizers, Carbon duct-mounted units for formaldehyde, and PTAC units using UV and PCO), and germicidal UV-C inactivation (Lightstick Gold with UL60335-2-40 compliance, Lightstick, Duality, VersaLight, 4Xtreme rooftop, Ultra-Flex, Nomad, and XL commercial-coil fixtures). Performance products such as the SST2 system transition and Furnace Riser are sold alongside the IAQ line to optimize HVAC SEER efficiency and filtration area.

The business sells exclusively through RectorSeal's B2B distributor and rep network, reaching HVAC contractors, installers, and building professionals across U.S. residential and commercial markets; products are not sold direct-to-consumer. Pricing is quote-based under a Minimum Advertised Pricing policy, and the company supports channel partners with product catalogs, technical specifications, and the RectorSeal Academy training platform. Customer segments are horizontally segmented by building type (residential homeowners as the primary segment; commercial and industrial buildings as secondary), with use cases spanning central home filtration, commercial rooftop and large-coil UV coverage, and tight-space PTAC installations.

Dust Free employs 101-250 people and operates as a mature, channel-mediated industrial hardware brand within a publicly-traded parent group; no independent revenue, funding history, or management roster is disclosed.
