5. Bluonics 110W UV Ultraviolet Sediment Carbon Well Water Filter Purifier System Review
Bluonics 110W UV 3 chamber system works to purify water in 3 distinct stages. It differs from other ultraviolet water purifiers as it works with 2 UV bulbs. Stage one brings the water through a 5 Micron Sediment Filter. Anything related to sand, dirt, dust, rust are removed at this stage.
Microns are approximately .00004 inches, or one millionth of a meter. A lot of water moving through very tightly packed spaces. The Bluonics system flow rate is impressive at 24 GPM. The sediment process prepares the water to run more efficiently and effectively through Stage 2. When the water is sediment-free, Stage 2 introduces the water to a 5 Micron Carbon Block Filter.
Carbon is the powerhouse that removes chemicals, additives, and bad taste and odor. The final pass through Stage 3 is Bluonics powerful ultraviolet light. This process sterilizes the water and removes bacteria, most notably E. coli and Giardia and many other contaminants.
Many outdoor enthusiasts and consumers living near or off the grid appreciate the double UV light technology and have established Bluonics as a staple UV water purifier in wilderness homes and cabins to combat animal feces and urine collection in private well water sources which grow E. coli and other harmful bacterias.

6. Bluonics 4 Stage Water Filter UV Light Purifier for Bacteria Under Sink Filtration System Review
This compact Bluonics 4 Stage ultraviolet water purifier fits under the kitchen sink, using a 3 chamber filtratration system, with the UV light purifier acting as the 4th chamber and last point of contact as the water enters the faucet.

It’s small enough to use in RVs, boats, office break rooms and mobile homes. 1 sediment filter removes dirt and sand while two additional carbon-based chambers work to eliminate bacteria and germs.
Although this affordable and portable filtration system is best for smaller home water systems and work best under the sink, it isn’t the best for long term water filtration solutions.

2022 Buyers Guide to the Best Ultraviolet Water Purifier
The day isn’t going at all as planned and at every turn people are acting strange. The comment, “It must be something in the water!” comes to mind. Although this time-honored expression speaks to a humorous metaphor; in the literal sense it means that germs, unhealthy microbes and dangerous bacteria are hanging out and reproducing in the home’s water system.
Whether resistant or powerless to address the unhealthy and sometimes hazardous issues, cities and local municipalities are only required to uphold certain standards for water delivery to homes and businesses. They are not responsible for the water’s purity. Installing a water filtration system works as a first line of defense.
Prior to installation, understand how much water needs to be treated and what flow rate is best for the water being delivered to each corner of the home. A smaller system can overheat and fail if it can’t keep maintain consistent flow rate. A larger system can become a costly annual expense as many filters need changing.
Larger systems also require more part replacements and cleaning, so it’s good to be mindful by recording future cleaning and filter replacement times, or buy an additional manufacturer recommended smart-timer and let the system decide when replacement and cleanings are required. An efficient-running UV system is paramount to clean, purified water.
Light lives on a spectrum. Ultraviolet light lives between visible light which humans can see, and x-rays, used in medical practice. Black light posters glow with the use of an ultraviolet light bulb. Skin drinks in natural ultraviolet light from the sun, allowing tissues to absorb the healthy benefits of vitamin D and stay summer-bronzed. The downside of sunbathing is too much exposure to Ultraviolet light damages DNA. This damage stops healthy cells from growing, which can lead to skin cancer.
Much like exposure on the skin, ultraviolet light distributes into the water, entering the damaging DNA living in hazardous microbes and bacteria, eliminating contaminates and stopping the reproduction cycle. When used properly, with the home’s soft-water or charcoal-activated water system, attached directly into the plumbing under the sink or at the connector of the home’s water intake, an ultraviolet light water purifier is a great addition to clean and purify water, naturally and safely.
But there are a few factors to consider before installing a UV water purifier.
3 Main Points to Consider:
- Test the water before investing in a UV filtration system / Keep the system clean – Before installing any type of filtration system, test the well water with a professional water testing kit. Most manufactures how “clean” the water should be before running it through the filters and UV light. Understand the exact cleaning and care instructions for the filtration system to keep it running efficiently. Depending on climate, run time and water table, the system may need extra maintenance.
- Research reviews & ask questions in online forum – Consumers whose homes run on well water know the best tricks, tips and hacks. Many experiences with the UV filtration systems reviewed speak to the installation instructions not being clear, and many runs back and forth to the hardware store searching for the correct pipe fittings and o-rings. Knowing how to install the filtration system correctly is important to avoid overheating the water, breaking the UV light bulb, system failure and paying out of pocket for a plumber or electrician to make repairs.
- Check the warranty / Customer support – The delicate pieces that make up a UV water filtration system are expensive, and the cost to replace a system with 4 or more filters can become a time management nightmare. Shop for a water filtration system backed up by at least a one (1) year warranty and a 24/7 customer service department. Ask the company what parts are replaceable within the warranty period as some companies will send replacement pieces and UV light bulbs at no cost.
Do UV water purifiers kill viruses?
One of the best features of an ultraviolet water purifier as part of the home’s water system is it’s powerful 99.9% elimination rate of water-borne illness viruses including Typhoid, Cholera, Hepatitis and Flu. The intensity of the UV light rays works its way into the harmful cell’s DNA, destroying its ability to reproduce.
UV light works more powerfully than the sun, emitting 254 nanometers of ultraviolet rays. A nanometer is a unit of measurement. It equals one-billionth of a meter. Break down the measurement of the “pieces of light” radiating through the water, and that is a powerful amount of radiating UV rays working to purify. In terms of the electric charge flowing through the water to kill the virus: 1 kilowatt equals 1,000 nanometers. That amounts to a lot of electricity usage to disinfect the water.
But that usage doesn’t mean a higher energy bill, since UV water filtration systems use the wattage of a 60W light bulb! Clearly, adding an ultraviolet water filtration system to kill harmful bacteria and viruses is a wise investment.
Is UV treated water safe to drink?
Ultraviolet water filtrations systems are reliable and safe. No to mention fool-proof. Water moves through the home at some point, 24 hours a day, 7 days a week. UV filtration is working around the clock to keep water purity and quality at its very best. The addition of a UV filtration system isn’t just environmentally-friendly; it never requires added chemicals, and it’s virtually low-to-no sodium free solutions makes drinking water safe. Ultraviolet light water filtration is also FDA approved.
Best Ultraviolet Water Purifier Reviews (2022 Buyers Guide):
Final Thoughts on Buying a UV Water Purifier
When deciding on adding an ultraviolet water filtration system albeit under the kitchen sink or to a water filtration system already in use, first and foremost, consider the source of the water entering the home.
Call the local water municipality for important information on the water table. Get an inspection of the well or other any other water source supplying water to the home. Knowing what kind of water being treated before adding the system is key.
It’s important to understand if the UV filtration system functions better with the home’s pre-filtration or post-filtration system already in place. It doesn’t remove man-made contaminants, heavy-metals, chlorine and salts. The water entering the home must be treated and clear, not murky. Otherwise the investment made – and sometimes costly – to treat the water with UV light may cause a system failure. In the long-run, additional maintenance and calls to the plumber to reset the water table could cost more than the system itself.
