What does a UV light do in a humidifier?
The job of a UV light in the humidifier is basically to sterilize. Most times, the humidifier is infused with a light bulb, in which when powered, released UV rays which go on to interact with the water, killing microorganisms like viruses and bacteria that are too small to be held by a filter, but very much harmful should they find their way into the body.
With this function, the humidifiers primary purpose is not just to increase moisture content in the air, but to instead do it in the safest way possible, riding the environs altogether from harm.
Does UV light kills molds and other Microorganism?
It was earlier said that UV lights are very effective against microorganisms that could cause infections, and these microorganisms ganged up in millions is what becomes more visible infections like bacteria build-ups and molds.
When UV light is released to the water, it brings with itself the same power of sunshine, killing the organisms that cause the visible buildup result, and as a result killing the buildup itself. In essence, UV light is able to kill mold as far as it touches it, treating both the one you can see and unseen (Mold spores).

Features to consider in choosing the best humidifier with UV light
- UV light:
It shouldn’t be a surprise that possessing a UV light is an essential quality to consider when choosing the best humidifier for clean mist generation purposes. Though humidifiers are ordinarily safe, units with this feature take safety to a whole new level, attacking contaminants at a micro level, and only allowing clean water to be mystified.
Although the possession of a UV function is essential, it is also necessary to consider the capacity of the unit, precisely how much room space it can serve, to determine if it would actually be able to do the humidification job. This quality gives preference to the humidification work, rather than how clean the mist would be.
- Antimicrobial infused tank:
Another level of cleanliness a humidifier can attain, is in its ability to refute the common buildup of mold and bacteria in its tank over time. This is where this feature comes in, and it is convenient to ensure a clean, safe mist while reducing the amount of time spent on and between maintenance.
- Quiet operation:
This is responsible for how noisy or quiet a unit would be in service, and of course, anyone would pick a quiet product than a noisier one. Quiet humidifiers also have the advantage of being able to be used anywhere in the home, ranging from the sitting room to bedroom, and can even be left running over the night, without disturbing sleep.
humidifier with uv sanitizing light – Pros and Cons
There are several pros and cons to using a UV infused humidifier, and they are;
What we like:
- Highly effective:
The significant advantage of using devices with infused UV light is due to how effective they are in doing the job. As far as it is able to come in contact properly with the water, UV lamps are well and able to kill up to 99% of microorganisms, including bacteria, viruses, and mold.
- It can be easily replaced:
UV bulbs mostly have an expiry date, where the light produced becomes too weak to make the desired impact, becoming relatively a glowing bulb in the unit. It can, however, be easily replaced by purchasing the exact model from the nearest electronic store.
- Useful against airborne contaminants:
The UV light doesn’t only kill contamination in the water, but rather also anyone that finds itself in the air surrounding it. It is, therefore, a double-edged sword, eliminating both waters as well as air contaminants, in a win-win situation for the user.
- Doesn’t consume energy:
Placing a UV supported humidifier, beside a non UV supported one, there is basically no difference in energy consumption between the two. This means that the bulb raises your safety by a higher level while adding next to nothing on energy bills at the end of the month.
What we dislike
- Being a light bulb, its surface is very attractive to dust and other floating particles, therefore making it in need of frequent cleaning to be effective. It is also essential that the unit is off before this act is carried out.
- Though UV light is very effective against mold, bacteria, and mildew, when it comes to viruses, it is far less effective due to the nature of the coated body possessed by this organism.
- Another downside of devices with only UV light is the fact that it is only able to kill organisms while doing next to nothing to particles. For this reason, these devices need to be used with a filter for the complete cleaning process. It also does very little to prevent mineral builds over time; therefore, it would still need physical intervention for proper maintenance.
- The live span of UV bulbs is pretty short. Depending on the manufacturer and device in question, some could last as much as a year before needing replacement, while others can only manage about 6 months.
- Also, depending on the device and manufacturer, some UV bulbs can be relatively expensive to replace, and there are even several cases of the bulbs almost costing half of the price for purchasing the device.
Final Verdict : Best Humidifiers with UV light
Our best pick from tests and performance on the best humidifier with uv sanitizing light is going to be the Pure Guardian H5450BCA. The device has a pretty decent water tank capacity, but an extremely impressive runtime, which is mainly due to the unique design that helps it maximize water over a long period of time. It is also suited to large-sized rooms and releases very clean mist due to an antimicrobial tank, as well as the UV-C light.
The Honeywell HCM350W product is also a safe bet for picking, on devices with the best UV light. Of course, it comes as an adequate UV cleaning capacity, as well as an antimicrobial, infused tank, keeping the mist clean and safe, but it is, however, suitable for small to medium-sized rooms only.
