Buying an air cleanser to counter the high polluting of the environment levels? This air cleanser buying guide aims to help you take an informed decision.

Buying an air cleaner is tricky. With no industry standards set up in India, individuals are at the mercy of the brands. The values of air purifiers can are normally taken for anywhere between Rs 8,000 and Rs 1 lakh. There are many factors to consider before buying an air purifier. It’s very important to endure the specifications of each model and never blindly believe the sales executive. This buying guide is designed to help you take an informed decision.

What to remember first

Prior to you heading off to buy an air cleaner, note the following:

  1. Note the dimensions of the space (preferably in square metres) in which you need to install an air purifier
  2. Observe that portable air purifiers are meant to focus on only one room
  3. Avoid Ionizers, UV light-based models. These home air cleaners release ozone as a byproduct which have negative effects.
  4. The expense of replacing air conditioner filter and electricity costs must certanly be kept in mind. For best results, air purifiers should always be kept running always.

Certifications to consider

  • There are two standards- AHAM (American) and China certification- which can be taken seriously in the industry. Most air purifiers that are offered in India would not have any of these certifications. Both the certifications ensure the very least quality and gratification standard for an air purifier model.
  • Some popular AHAM Verifide brands are Blueair, Bosch, Electrolux, Honeywell, LG, Philips, Sharp, Whirlpool amongst others. Keep in mind that all models from all of these brands may not be certified.
  • Some brands like Xiaomi follow Chinese GB/T 18801 Air Purifier standard.

Sort of Filter

  • The product quality and style of filter determines the effectiveness of an air cleanser. Specific filters target different aspects of air. Probably the most commonly available filter type is HEPA (High Efficiency Particulate Air). It may filter most (up to 99.9%) air borne particles of small sizes of up to 0.3 microns. For general usage, HEPA filters do the trick.
  • Some brands provide ultrafine particle filter along with the HEPA filter to a target particles even finer than 0.3 microns (Divide a hair strand into 240 pieces and the width of 1 such piece is the same as 0.3 microns). Remember that HEPA filters try not to remove odour.
  • To target odour, you’re going to have to decide for an activated carbon filter along the regular HEPA filter combination. There are numerous forms of activated carbon filters. A number of them are light mesh-like which prevents cooking odours. On the other hand, some filters offer activated carbon pellets that may remove gaseous and chemical odours.
  • Some brands even let you customise the filter according to your requirement.
  • Air cleanser filters usually do not kill air borne germs and bacteria in general. You can look out for filters with antibacterial coating. However, avoid UV light-based models.
  • Few air cleaner models offer a washable pre-filter to fully capture dust and other large particles. Choose for a model with pre-filter since it escalates the life span of this filter inside.

Performance

  • The performance of a particular air cleanser model is rated by its coverage area, Clean Air Delivery Rate (CADR) and Air Changes Per Hour (ACH). While brands will boast about the CADR and coverage of a certain air cleaner model, they will certainly elect to remain silent on the ACH. This is something you really need to ask to see before buying an air purifier.

What exactly is ACH?

  • Air Changes Per Hour (ACH) is basically how many times an air cleanser can clean the atmosphere of their claimed coverage area in an hour. This is really important because pollutants constantly enter your living space in addition to air purifier needs to constantly clean the atmosphere. Given the pollution levels in Delhi, choose for an air purfier that offers 4 ACH. What this means is the air purifier can perform washing the air regarding the entire claimed area four times in an hour or so or every fifteen minutes the air inside is wholly replaced.
  • The catch let me reveal brands tend to hide the ACH rating while showcasing an elevated coverage area and CADR. If an air purifier can cover more square feet however if its ACH is around one or two, then it will likely be less efficient. Some brands like Blueair offer 5 ACH.

Other items to notice:

  • Price of replacement filters and their lifespan. Filters usually cost within the variety of between Rs 1,500 and Rs 2,500 with a lifespan of approximately half a year. Also, don’t neglect to check into the option of filters.
  • Considering electricity costs, attempt to search for an air purifier with energy star ratings.
  • Noise levels must certanly be around 35 decibels if the fan is running at the very top speed. Do not choose for models with above 55 decibels rating. It is commonly disturbing while asleep.
