These bulbs are a perfect replacement in our HVAC system. The price allows me to swap them out every 12 months to keep mold away from the system and keep the air clean. I buy all filters for HVAC, fridge water, and car cabin from Discount Filters. Their customer service is exceptional as well.

They are UV bulbs...The only negative is they usually burn out within 2 years. So I recommend ordering a few to have on standby.

Frequently Asked Questions

What are UV lamps and how do they work?

Ultraviolet (UV) lamps are also called UV bulbs or germicidal lamps. A UV system can be added to your existing heating/cooling system near your AC evaporator coil or directly in the airstream. UV light is germicidal, which means it deactivates the DNA of microorganisms like bacteria, viruses, and other pathogens, short-circuiting their ability to multiply and cause disease and unwanted odors.

How often should I change my UV bulb?

Annual UV bulb replacement is recommended annually. Over time - the output intensity of UV germicidal lamps will decrease. So - even if an old bulb is lighting up/turning on, it may not be nearly as effective as it once was.

What’s the difference between UV and UVC?

"UV" is a general term for ultraviolet. The "C" in "UVC" describes the specific UV wavelength that has been found to have germicidal properties. UVC or UV-C light is traditionally referred to as "germicidal UV" because of it’s proven ability to kill bacteria, mold, and fungi.

Is UV light bulb replacement easy?

Yes. Consult the owner’s manual for information on replacement. Usually, UVC bulb replacement is a simple matter of turning off power to your HVAC system, removing a few screws, and inserting a new bulb. There is no reason this can’t be a DIY project.
