How To Select The Best 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.
