If you've ever walked into your home and immediately noticed that smell—whether it's the dog, last night's fish dinner, or that vague mustiness you can't quite pinpoint—you know how frustrating it is when the air just won't clear. The Greentech pureAir Active HEPA+ Room is engineered specifically for families who refuse to settle for air that smells "okay" or feels heavy with allergens. Designed for real‑world living rooms, bedrooms, and open spaces up to 575 square feet, this isn't just another filter in a box—it's a complete air transformation system.
Here's why it works when others don't: Most purifiers rely on a single filter to trap particles and hope for the best. The pureAir Active HEPA+ Room attacks air quality problems from multiple angles simultaneously.
Its high‑efficiency HEPA filter—coated with revolutionary ODOGard technology—doesn't just capture fine particles, pollen, and pet dander. It neutralizes them and destroys odor molecules on contact, preventing them from ever cycling back into your breathing space.
Meanwhile, bipolar ionization and photocatalytic oxidation (PCO) actively break down airborne contaminants, VOCs from cleaning products and furniture, and even microbes that other purifiers miss entirely. The result? Air that doesn't just look cleaner on paper—it feels and smells genuinely fresh.
This unit transforms life for:
-
Pet-loving homes where fur, dander, and litter box odors are non-negotiable facts of life—but breathing problems and lingering smells don't have to be.
-
Empty‑nesters and retirees who deserve to breathe easier without constantly dusting furniture or worrying about respiratory irritation.
-
Allergy sufferers who are exhausted from guessing whether their purifier is actually working or just making expensive noise in the corner.
The difference you'll actually notice: Unlike those basic "fan plus filter" boxes from big‑box stores that force you to guess if they're working, the pureAir Active HEPA+ Room shows you. The vibrant color display spells it out in plain English—GOOD, FAIR, or POOR—and automatically increases fan power the moment your air quality drops. When your teenager burns popcorn or the dog comes in from a rainy walk, you'll see the system respond in real time. And because ODOGard actually bonds to and breaks down odor molecules instead of just covering them up with fragrance, those stubborn smells vanish completely instead of returning an hour later.
Why A‑1 stands behind this model: This is a purifier built for the long haul, not planned obsolescence. The intelligent display shows you exactly how much life remains in your HEPA filter, PCO cell, and ionization module—no more guessing games or surprise failures. With quality construction, genuinely smart controls, and components designed to be replaced rather than forcing you to buy a whole new unit, this represents real value for Lexington homeowners who believe in buying right the first time. When you factor in years of cleaner air, fewer allergy medications, and a home that actually smells welcoming when guests arrive, the investment pays for itself.

FAQs
Is this good for pet odors and dander?
Absolutely—and it's one of the best investments pet owners make. The HEPA/ODOGard filter captures every bit of pet hair and dander floating in your air, while ODOGard permanently neutralizes the odors from dogs, cats, and litter boxes at the molecular level. No more masking smells with candles or sprays—just genuinely fresh air.
How big of a room will it handle?
It's designed for spaces up to roughly 575 square feet, which means it can tackle most primary bedrooms, living rooms, and open‑concept family areas with ease. If you have a larger space, ask us about the Pro model.
Care and maintenance highlights
- Replace the HEPA/ODOGard filter on the manufacturer's recommended schedule or sooner in high‑odor or high‑dust environments—the display will tell you exactly when.
- Keep the air intake and outlet grills free of heavy dust buildup so airflow stays strong and efficient.
- Check filter‑life indicators on the screen and app regularly so you can plan replacements proactively instead of being caught off guard.
