Abatement Technologies CAP500-UVP Residential UV-C + Ozone HVAC Air Purifier

Your HVAC system runs 24/7. So does the mold, bacteria, and odor building inside it — unless you do something about it.

The Abatement Technologies CAP500-UVP is a duct-mounted UV germicidal air purifier that installs directly into your central HVAC system and runs continuously — destroying bacteria, mold, viruses, and odor-causing compounds every time your system cycles air through the house. No filters to swap monthly. No counter space consumed. No portable unit to move room to room.

Just whole-home germicidal protection, built into the system that already moves air through every room you live in.

This is the UVP model — the "Plus" version that adds controlled ozone output for homes with persistent odor problems. If your issue is mold smell, pet odor, smoke, or musty water damage — this is the model for you. (Need UV without ozone? See the CAP500-UV here.)

Who This Is For

The CAP500-UVP is best suited for homeowners dealing with one or more of these:

• 🐾 Pets — dander, odor, and the biological load that comes with animals in the house
• 💨 Smoke — tobacco, wood-burning stoves, or wildfire smoke that's penetrated the ductwork
• 💧 Water or moisture issues — past flooding, high humidity, or chronic condensation on the coil that leads to mold and mildew smell
• 🌿 General indoor air quality — older homes, allergy sufferers, or anyone wanting a proactive layer of protection against airborne pathogens

Installation requires cutting a small hole in your ductwork or air handler cabinet and wiring to a standard 120V outlet. If you're comfortable with basic HVAC work and electrical, this is a manageable DIY project. If not, any HVAC technician can install it in under an hour — and many already spec this unit by brand.

How It Works

☀️ Germicidal UV-C — The Same Technology Used in Hospitals

UV-C germicidal irradiation has been used in hospitals, food processing facilities, and pharmaceutical manufacturing for over 60 years to control airborne bacteria, mold, and viruses. The CAP500-UVP brings that same technology into your ductwork. The 1,950 μw/cm² UV-C lamp irradiates the interior of your air handler continuously — destroying microorganism DNA so they can't reproduce or survive. Every cubic foot of air that passes through your HVAC system gets exposed.

⚡ Ozone Odor Elimination — Targeted, Contained, Effective

The UVP model's "Plus" lamp generates a controlled amount of ozone inside the ductwork. Ozone is a highly reactive molecule — it binds to and neutralizes odor compounds at the molecular level, not just masking them. The reaction happens inside the duct, and the ozone dissipates before reaching your living space. The result: odors from pets, smoke, and water damage are chemically broken down, not covered up.

This is fundamentally different from whole-room ozone generators, which flood living spaces with ozone at levels that can be harmful. The CAP500-UVP's ozone output is designed to work within the contained environment of your duct system — not in occupied rooms.

🔴🟢 Lamp Status Indicator — No Guessing

A built-in visual indicator tells you exactly where your lamp stands:

• Green — Lamp is operating within acceptable range. You're protected.
• Yellow — Lamp output is declining. Schedule a replacement soon.
• Red — Lamp is inoperable. Replace immediately.

An audible chirp alarm also activates when the yellow indicator appears — so even if you don't walk past the unit, you'll know it's time.

What It Destroys

• ✅ Bacteria (including mold-forming species living on the evaporator coil)
• ✅ Mold and mildew
• ✅ Viruses
• ✅ VOCs (Volatile Organic Compounds)
• ✅ Pet odors
• ✅ Tobacco and smoke odors
• ✅ Cooking odors
• ✅ Musty water and moisture odors

Technical Specifications

Installation Overview

The CAP500-UVP mounts into the ductwork or air handler cabinet of your central HVAC system — typically near the evaporator coil for maximum effectiveness against coil mold and airborne pathogens.

What's required:

• A small access hole cut into your supply plenum, air handler cabinet, or return duct
• A standard 120V power outlet within reach (most air handlers have one nearby)
• Basic tools — drill, hole saw or tin snips, screwdriver

Comfortable with HVAC and basic electrical? This is a realistic DIY project. Abatement's installation instructions are straightforward, and this unit is regularly installed by homeowners familiar with their systems.

Not sure? Call your HVAC tech. Any licensed HVAC contractor can install this in under an hour. The unit is well-known in the trade — if your tech isn't familiar with Abatement Technologies, that's worth noting.

Note: This product ships standard ground (no freight required). Arrives ready to install.

Annual Lamp Replacement

UV-C output degrades over time even when the lamp appears to still be lit. Abatement recommends replacing the lamp every year (approximately 9,000 hours of operation) to maintain full germicidal effectiveness. The status indicator takes the guesswork out of timing.

OEM replacement lamps available here:

• UVP425 Replacement Lamp — Single
• UVP425 Replacement Lamp — 4-Pack (best value)

Important: The UVP425 is the correct lamp for this model. The UV425 (used in the CAP500-UV) does not generate ozone and is not interchangeable for odor-control applications.

CAP500-UV vs. CAP500-UVP — Which Do You Need?

If odors aren't your primary concern, the CAP500-UV handles germicidal protection without ozone.
