Who Its For

Great For HomesWithout Ducted Systems

If your home or unit doesn’t have central ductwork, that doesn’t mean you need to live with unclean air. These are the spaces a plug-in purifier is built to handle.

Apartments & Rentals

No ductwork access, no permission needed from a landlord to install anything, it simply plugs in.

Mini-Split Homes

Ductless heat pump systems don't move air through a central return, so whole-home duct purification isn't an option.

Additions & Bonus Rooms

Rooms added after the original HVAC layout, like converted garages or sunrooms, that sit outside the main duct run.

Wildfire Smoke & Odors

Fast, single-room protection against smoke, pet odor, and allergens without waiting on a duct install.

Active Air Quality

Featured Air Purification System

Meet the Beyond Guardian Air

For homes and units without ducted HVAC, Beyond Guardian Air is the portable purifier we recommend most. It combines ActivePure Technology, True HEPA filtration, and activated carbon in a single freestanding unit. No installation, no ductwork, just plug it in and it goes to work covering up to 2,500 sq. ft.

True HEPA Filtration

Captures 99.97% of particles as small as 0.1 micron.

ActivePure Technology

24/7 active purification of the air in the room, not just what passes through a filter.

Activated Carbon

Reduces VOC gases, smoke, and odors without producing ozone.

Portable & Whisper-Silent

Lightweight, easy to move room to room, quiet enough for bedrooms.

Ducted Vs. Plug-In

Two Different Jobs, Both Done Right

In-duct air purifiers treats a home’s ductwork. Beyond Guardian Air treats a single room or space with no ductwork required. Here’s how the plug-in unit compares to basic portable purifiers.

					Had Cline’s clean our air ducts and test our air quality after close proximity to the fires.  Scheduled us quickly and the service techs (Grayson and Perkins) did a… read more thorough job, while helping us understand the process.  Great experience.  Thanks!
