Types of Air Purifiers
1.UV Air Purifiers:
UV stands for ultraviolet light – and you guessed it – this kind of air cleaner uses UV lights to destroy microorganisms like bacteria, mold, and viruses.
While you might deduce that this kind of high-tech purifier is the best choice for your home, also consider that these devices have limited functionality, specifically there are many different kinds of pollutants it cannot remove from the air.
Because of this little fact, some people choose to use this kind of purifier in conjunction with another. Some well-known brand names for UV air purifiers include Ionic Breeze and AllerAir.
2.Ionizing air purifiers:
This type of air cleaner uses a different process to cleanse the air – an ion generator. Electric charge from the ion generate causes pollutants to bind together. Once bound together, the micro-particles form large particles.
These purifiers typically come with a collector plate because otherwise the particles will stick to every surface of your home and cause another problem – dirt. Some examples of ionizing air purifiers are the Surround Air and the Ionic Pro.
3.HEPA Air Purifiers:
This kind of air purifier earns a reputation as one of the best for its efficiency. Scientific studies have revealed that HEPA purifiers are responsible for removing 99.97% of air pollutants.
Many sufferers from asthma or allergies use these devices as their air purifier of choice. Some popular choices are Blueair, Hunter QuietFlo, and Honeywell purifiers.
4.Carbon Air Purifiers:
are highly effective with gas, smokes and odors, but not as effective with allergens, dust, and bacteria. Carbon air filters are comprised of very tiny extremely absorbent pores. They chemically react to the particles that pass through them. Larger particles are stuck in the many pores.
5.Ozone air purifiers:
work like an ionic but it is most effective on odors. Ozone is a highly reactive, unstable molecule that oxidizes anything it comes in contact with.
The ozone purifiers cause a chemical reaction which breaks down the pollutants, but the pollutants turn into other pollutants, which is the drawback of these machines. It is advised that you run the machine on low, and then open the window to release the ozone.
How to Buy the Right Air Purifier?
(a) Where will you use the machine? – Most models are pretty portable, which you can rotate usage in various parts of your house. You can even bring it on vacation, there are models that weigh as light as 4 pounds, although the quality may be a bit compromise, it does do the basic things an air purifier should.
If you are looking to put it in a permanent place in your house (like the living room), you can get the regular sized type. Position the air purifier close to a socket outlet and make sure it is at least 3″ from the wall for air circulation.
(b) Unit’s capacity – This will depend on the size of the area where you will put your air purifier. Usually machines are rated for its efficiency based on certain room sizes, so you cannot expect a model built to circulate a 300 sq feet area to perform the same way in a 800 sq feet area.
The number of times per hour that volume of air passes through the unit also determines its efficiency. Therefore, before shopping, you should measure you’re the area’s dimension and buy accordingly to the coverage area of the model (or higher). You may want special features like multiple settings, so look for a model that has it.
(c) Type of Filtration – The more filtration devices in a purifier makes it a better model. There is the pre-filter and the Hepa (known as carbon filters). The pre-filter will trap larger particles of dust, and then the Hepa will further remove about 98% of airborne particles. Each stage of filtration means more removal of the air irritants, hence the better air quality.
(d) Availability of Filters – It is advisable to buy from the makers that have most buyers for uncommon brand may give you difficulty in finding replacement filters. Although the manufacturer has a recommendation as to the timeframe a filter will last, it is good to have a rule of thumb that Hepa filters can last about 17-35 months and a pre-filter lasts about 7-14 months, depending on the size of your purifier. Do get a spare replacement set when you purchase your entire purifier.
(e) Certification and Standards – Air purifiers that come with multi or Hepa standard filters are very pricey. Therefore, be very alert when purchasing. Make sure you check the unit for certification by the authorized party, efficiency ratings and that it meets the standards of its line. You should also find out if there is a parts list because it could be of help when you need replacements later.
(f) Making the most out of it – Hepa filters, as you would have known by now, are more expensive. In order to protect it, change the pre-filter regularly.
An air purifier will work more efficiently if the door is closed and getting a unit built for a larger circulation area can better clean a small room.
Another tip is to set it to ‘quiet’ at night and ‘high’ for daytime if you put the unit in a bedroom. An air purifier should run throughout the day so that you get better quality air all the time.
Benefits of Having an Air Purifier
One of the main benefits of air purifiers is simple – you can actually breathe more easily. How do these devices work? Air cleaners use filters (also called collector grids) to purify the air inside your home. You might be surprised but microscopic allergens like dust, mold, mildew, pet dander, pollen, and chemical pollutants frequently “live” in the same indoor area as you do. And air pollutants can come from practically any source – furniture, rugs, carpets, toys, pets, even common household cleaning products.
If you suffer from allergies, you already know that microscopic, invisible-to-the eye particles can make it miserable to breathe.Symptoms you may experience include sneezing, watery eyes, difficulty in breathing, and a runny nose. While it is one thing to experience allergies outside, it is something entirely different to have to suffer in your own home. As far as other health concerns, children and the elderly are particularly susceptible to illness when they breathe unclean air.
Maybe you’re not dealing with uncomfortable health conditions exactly. Maybe you are just sensitive to strong, hard smells or offensive odors.Simple things like leftover food odors, cigarette smoke, and dog or cat smell can be enough to drive your olfactory senses insane. The great thing about air purifiers is the ability to remove the offensive smells and leave your air feeling cleaner and fresher.
