Air purifiers available from the market vary from model to model by the specific purposes for which they are designed. What air purifier is best for you will be determined by the kind of indoor air impurities you want eliminated. Ionizing Air Purifiers If removing smells is your priority, an ionizing air purifier is worth considering. Ionizing air purifiers are said to be the most effective schemes available for clearing the air inside a smoke-filled room or for banishing unpleasing odors. One ordinary brand, priced at $300, is the Ionic Breeze. This air purifying system works by emitting negatively charged ions that bond with in a positive manner charged particles, including those that make up smoke and bad smells. The bonded ions become exceedingly heavy to float, and drop to the purifier’s collection plate. These fallen atoms may be wiped away by a cloth. Ionizing purifier schemes don’t remove dust in the air, and Consumer Reports has issued a statement to this effect. Low Ozone Air Purifiers Low ozone air purifiers oxidize pollutants, resulting in purer indoor air for us to breathe. If you’re concerned with regards to odors, a low ozone air purifier is probably not what you need as it have a tendancy to give off a metallic smell. Be admonished likewise that these purifiers emit ozone, which may be destructive to the health, specially when inhaled in high concentrations. Low ozone air purifiers cost when it comes to $500, and are best when combined with ozone air purifiers. Air Purifiers With Air Filters A purifier outfitted with an air filter like the 3M Filtrete may be what you need if the smells you are attempting to eliminate have to do with pet dander and dust. Costing around $70, air purifiers with air filters are best for confined spaces, so having a few air filter purifiers for your home might be a good idea. The filters require replacing each quarter. HEPA Air Purifiers The ordinary high-efficiency particulate air (HEPA) purifiers are good at removing airborne allergens, dirt and dust, but they don’t do as well on smoke and smells. HEP air purifiers are likewise higher-priced than most air purifiers. UV Air Purifiers Air purifiers based on ultra-violet (UV) light engineering kill viruses and bacteria, but are not exceptionally effective versus odors. UV air purifiers are the most complex of the air purifiers, and are ofttimes installed in air ducts where airborne microorganisms pass through. Because of their sterilizing effect, these systems are idealisti for hospitals and government buildings.

My first bulb started flickering and went bad just recently. Not doubting others troubles but ased on some of the other quality control problems I’ve read here I guess I’ve been lucky. My bulbs have worked great and fans arent completely quiet but not loud either. The manufacture does suggest replacing bulbs annually and I would agree. Seems after about a year they have lost some intensity due to their small size. In my opinion the unit could be a larger with bigger more intense bulbs to maximize larger room sterilization. 32 of 36 people found the following review helpful. After less than a month of use, the bulb started to flicker and died in one unit. I am very familiar with UV-C sterilizing lights and have used them reliably for years in koi pond, potable water, and HVAC applications. I’ve never seen a bulb fail so quickly. In fact, quality UV bulbs typically last for several years even though their effectiveness diminishes over time. Note, that the bulbs are extremely expensive for UV C applications. Additionally I find the fan units of these devices to be very loud, so much so that they cannot be used in a room if the room is occupied, and certainly not in a bedroom. I measured the sound at 5 feet at 50 decibels. And yes I take sound measurements professionally. Thats 4 sones! The industry standard threshold for bathroom fans for example is one sone. I have not yet disassembled one, but expect to find poor construction and cheap components. I don’t feel I have received a quality product for the price. The concept is great, and there is a market, but the quality of this particular product is not at a marketable level in my opinion. 29 of 33 people found the following review helpful. What it does do is blast viruses and bacteria with UV light to break them up and render them harmless. The advertising is correct: my wife works in a lab, and this is the same method of air sterilization used in hospitals and labs. The narrow tube in the middle of the Germ Guardian ensures that the air moving through it passes close to the UV light bulb and anything in it gets a strong dose of high-energy light. The slow fan speed also ensures that they spend a decent amount of time under the light. This is a feature, not a bug. The good news is, once they’re dead, they’re dead. Unless you have someone constantly sneezing and coughing right next to you, I wouldn’t worry about how quickly it filters. Just leave it running for a while, and the air you breathe will have far fewer living critters in it. I’ve owned mine for 3 years and while I can’t prove that it’s responsible, it does seem to work. The build quality is great, and it looks like they’ve added new colors to the line, in addition to “sci-fi stainless”. Four stars only because it could be a little quieter. |
Research UV-C before you rate this poor…its a very good product with some limitations
Poor construction, extremely noisy, bulb failure
