Air purifiers are an effective way to alleviate allergies, asthma, and respiratory issues. They clean the air of contaminants like dust mite feces, mold spores, pet dander, smoke particles, bacteria/virus/fungi cells.
According to Statista, in 2015, the global residential air purifier market had about 5.97 million units.
A HEPA UV air purifier has an additional feature: a special filter and ultraviolet light bulb.
But not all HEPA purifiers were created equal; most notably – they differ in their filtration technology (filter type, filter material) and replacement/maintenance cost. The following article will answer questions you may have about HEPA air purifiers with UV light.

1) What Are The Main Types Of Air Purifiers With UV Light?
HEPA air purifiers come in two varieties. They are explained below:
- a) Electrostatic filters (ES): These are the most popular type of air purifiers. Dust sticks to charged plates inside. While you can’t see it, this makes clean-up convenient; you wipe the outside with a damp cloth.
You also don’t need to buy new or replacement filters; wash them every 1-4 months (depending on use). Electrostatic cleaners are affordable, especially if you get one with a UV light.
- b) True HEPA filter: This is the most effective kind of air purifier at removing microscopic particles – like allergens/dust mites/pet dander/smoke particulates. They are more expensive to maintain than electrostatic cleaners.
2) What Kind Of UV Bulb Should You Get For Your Air Purifier?
Depending on the manufacturer, UV bulbs may vary in color (wavelength), output, and temperature. For instance, some are 25 watts while others are 35 watts. The higher wattage will emit more harmful UV rays, but there’s less risk of the bulb burning out.
You can find HEPA air purifiers with UV light in various price ranges – from $50 to over $500.
Whether you need a 25 or 35-watt bulb depends on the size of your room and how much airflow passes through it. Lower-wattage bulbs are meant for smaller spaces, while larger rooms require higher wattage.
3) How Do You Clean The Filter?
You most likely need to replace it every 3-6 months (more frequently than with an electrostatic purifier).
You can wash the device in warm water with a vinegar solution; however, you will still need to replace it every 3-6 months. You can also buy a new one after this period has passed.
4) How Often Do You Need To Change The UV Bulb?
Most manufacturers recommend replacing the bulb every 6-12 months to maintain top performance. You may find less expensive HEPA UV air purifiers with more frequent bulb replacement requirements (e.g., every 4-7 months).
The frequency depends on how much your room is exposed to direct sunlight. If you live in a hot, sunny location – the UV light will weaken faster than if you live in a cold, dark place.
If you live in an area with direct sun exposure, change the bulbs every six months. If you live somewhere like Alaska, California, or Florida – it may be wise to replace bulbs every nine months instead of 12.
5) How Does A HEPA UV Air Purifier Compare To An Ionizer?
Both purifiers emit ozone, but ionizers are even more ozone-heavy. That said, they have significant downsides – including being potentially dangerous for people with asthma/respiratory issues and not very suitable for people who spend much time indoors.
On the other hand, a HEPA UV air purifier is safe for everyone, has no ozone emissions, and is the perfect choice for people who spend a lot of time indoors. The purifier is best for medium-sized rooms.
6) What About A Germicidal UV Lamp?
These lamps are cheaper than air purifiers, and you can move them around as needed. However, they don’t offer ‘whole room’ coverage and must be within 3 feet of the pathogen to kill it.
7) Does UV Light Affect Pacemakers?
No, but it does affect some artificial joints, so people with these implants need to consult their doctor before using a purifier.
A good-quality air purifier with a HEPA filter and a UV light is a safe choice for anyone desiring protection from allergies/dust/pollen/smoke/pet dander/etc. If you wear a pacemaker, you must consult your doctor first.
8) How Long Do HEPA UV Air Purifiers Last?
These purifiers are durable and made of high-quality materials. More importantly, they have no mechanical parts that can wear or break down over time. It makes them ideal for people with asthma and other respiratory conditions.
Most manufacturers offer a 1-3 years warranty, so you know they stand by their product.
Conclusion:
HEPA UV air purifiers with a HEPA and a germicidal (UV) lamp provide robust protection against allergens and viruses. If you suffer from a severe allergy, asthma, or a respiratory condition – you’re going to love this combination.
