Buying Guide for Air Purifiers

So many explanations were imparted before. Details and features were given for readers to make their choices wisely, yet to arrive at a full proof conclusion, one needs to know and assess everything right from basics. So this guide happens to elicit certain clues, which will aid in making an in-depth analysis to buy the right purifier.

What is an Air Purifier?

The definition is pretty much evident from the name itself. But to lay it before common folk in simple terms it is a tool used to filter surrounding air of all unwanted toxic gases, dust, germs and impure vapors. So that inhabitant of premises incorporated with said device breathes in fresh air at all times without contracting any dust or unpleasant odor induced cough or headache. 

For asthma patients and people with an allergy against dust particles or pollen grains, this machine does a great deal of work to curb factors responsible for precipitating hypersensitivity reaction mechanisms while these people are still inhabiting that room or car installed with an air purifier.

In open areas itself where traffic is heavy or factories emitting polluting air particles are more in number, people may feel suffocated with a number of toxic gases entering their nostrils. There are cases of children having been locked inside a car with no open windows and no ac only to be found dead next morning because of a dearth in oxygen supply and higher levels of carbon monoxide in air passages. 

Need to provide purified air and requirement of devices like air conditioners to provide relief from excessive heat ushered in an era of discoveries, and patent right fights by renowned engineers and scientists like Charles Anthony Deane (1830), John Stenhouse (1860s), John Tyndall (1870s) and more.

Where to Place Air Purifier?

Air purifiers can be used in residential areas as individual units, or used in hospitals, factories, and offices on a wider scale in collaboration with air handler units (AHU) or HVAC units. These play a role in purifying industrial smoke and exhaust fumes from vehicles before contaminated air is released into the atmosphere. This way, these play a role in controlling environmental pollution. 

Apart from these applications, air purifiers also find a great deal of use in the fire fighting industry. For firefighters, divers and astronauts, it is a matter of utmost essence to keep on providing fresh oxygen for them to be able to respire. Considering they are required to pass through low oxygen density zones where there is a possible risk of death without proper air pumps and purifiers. 

Ventilators using air purifiers and humidifiers in ICU directly supply oxygen as the patient is unable to respire himself properly due to comatose or semi-paralyzed states. Infact John Tyndall was responsible for bringing the concept of a respiratory helmet with air purifying mechanism into existence for the fire brigade. John Tyndall improved a fireman’s helmet and respirator, specializing it to a filter device to be used against smoke. 

HEPA air filters were marketed first in the 1950s after their utility was acknowledged during the United States’ Manhattan Project. These HEPA air filters were first sold to be used domestically in 1963 by Manfred and Klaus, founder brothers of Incen Air Corporation ( currently IQAir corporation).

Types of Air Purifier Technologies

Depending on various techniques discovered to remove unwanted contaminants from atmospheric air, air purifiers are broadly categorized as:

  • Active air purifier technologies: These devices themselves make use of electricity or ultraviolet rays to ionize gases in air facilitating release of charged ions that attach themselves to particulate matter thereby, facilitating their removal or disintegration through further oxidation.
  • Passive air purifier technologies: These are filters which separate particulate matter from air by employing filtration techniques without expenditure of energy.
  • Purifiers with active and passive technologies: These air purifiers employ one of active energy-consuming techniques like Ionisers or PCO with passive filters like HVAC units or HEPA.

How to Clean Air Purifier?

  • The machine must always be unplugged before cleaning.
  • Be certain not to insert any waste into filter openings.
  • Permanent filters must be vacuumed every few months to ascertain their longevity.
  • Washable filters must be removed separately before cleaning.
  • The purifier surface must be cleaned with a soft clean moist cloth.
  • The exit pathway for filtered air can be cleaned of dust using a dry brush or cotton mesh.
  • The front outlet or grill must be removed separately and swiped with a wet cloth (not dipped in water). It should be dried before placing it back.
  • Normal HEPA and carbon filters are not meant to be washed. These are replaced with newer filters from time to time.
  • The inside wall of the purifier can be cleaned with a soft dry cloth, not with a wet one.

Precautions to take while cleaning an Air Purifier

  • Users must keep scrutiny on replacement indicators for filters from time to time.
  • UV lamps need to be replaced before expiry date with spares from the same brand.
  • Users must not use gasoline, petrol, oil, detergents, glass cleaner, polish, paint thinner, acetone, ethanol, and other domestic solvents to clean appliances.
  • Device needs to be switched off before unplugging.
  • In air purifiers with ionizers, appliances should be properly grounded with a three-pronged plug or with a ground adapter to safeguard users.
  • Air purifier preferably, must be used only within optimum temperatures of 4°C to 43°C.

Air Purifier vs Humidifier

Air purifiers serve an extremely significant role in the lives of citizens all over the United States. It has been proved owing to increasing concentrations of polluting agents in the atmosphere. Government and United Nations together work towards helping maintain natural standards of the environment. Yet, it is a humongous task to minimize air pollution and so citizens own a very crucial place in the heart of movement. 

With said objective, air purifiers are powerful tools for maintaining a healthy air quality of air indoors at least. In Fact people don’t only rely on air purifiers. They play their part by planting trees, organizing cleanliness camps, and awareness programs.

But now the question arises, how different is an air purifier from a humidifier? Infact what is a humidifier in the first place? More or less, everyone is acquainted with term humidity. the quantity of moisture contained in air is generally considered as humidity of air. Excess of anything is bad. 

Likewise, extremely dry air conditions can lead to problems pertaining to respiratory distress by causing conditions of dehydration, especially in desert areas or facilitating drying of skin in cold climates devoid of any moisture. Such low moisture atmospheric conditions, too, can tend to disrupt the general lifestyle of an individual. A device called a humidifier has been invented to counteract against this sort of condition inside a building. 

Humidifiers in layman terms are machines working on electricity, which improve moisture quantity in a room or entire house. These are normally employed in HVAC systems alongside air purifiers to improve overall quality of indoor air. Medical ventilators need humidifiers to provide best quality air to patients with dyspnoea.

Air Purifiers:

  • Gets rid of impurities from indoor air.
  • Makes use of filters to purify air.
  • Useful for patients suffering from asthma or having dust or pollen allergy.

Humidifiers:

  • Not meant to purify air.
  • Adds moisture to already dry air. No utility of filters.
  • Aimed at helping people with dry cough.

Some people use either of two devices, and there are others who make use of both these devices to ensure indoor air is sterilized as well as moist enough to not lead to discomfort.

Factors to consider before buying an Air Purifier

There is never just one reason to buy any article. A customer chooses an article based on benefits it has to offer as weighed against disadvantages it carries. following are certain questions customer needs to raise before selecting a particular brand of air purifier

Price range

Is the article affordable for users? The air purifier may be the best there is in the world, yet if a user doesn’t have sufficient funds to buy it, he simply should not invest there. Rather it will seem wiser to search for other similar air purifiers that may come within an affordable and cheaper price range.

Type of filtering mechanism used

What processes does air purifier employ to eradicate indoor air of all necessary impurities? This guide pretty much explains everything a customer needs to know with respect to all techniques employed during air purification. 

All techniques have a certain level of utility yet, the best air purifier to buy would be one which encompasses hybrid features with more than one filtration procedure taking part in air purification, for example, a combination of HEPA filter with activated charcoal and UV-C technology.

Efficiency and health

What percentage of air does purifier successfully manage to sterilize? How good is an air purifier to keep asthma attacks and allergic reactions at bay? If the price seems reasonable enough, users should check out the efficiency of air purifiers; if it can remove all categories of major impurities much more efficiently, especially in a house with little children always loitering around. 

For individuals with asthma and dust or pollen allergy, it is a matter of utmost concern that they use best quality air purifiers, which may work longer and efficiently to keep air pure and healthy.

Size & capacity it can handle

How small is the purifier? How large a room can an air purifier successfully function without breaking down?
For maximum users, the best choice of air purifiers will be that which consumes least space in a room. All air purifiers have their own limitations as to how much area they can cover during purification. Depending on the area the room encompasses, users should make a judicious choice for appropriate purifier.

Time is taken to assemble parts

How soon can users set the purifier together and get it to work? Not every individual is an expert at setting up machine parts together to be able to make it work. In these cases, models which do not require to be assembled together at all would be preferable.

Durability

How long should devices be used consistently to purify polluted indoor air? A user would find it to his or her liking better if the device can work consistently for a longer period of time without shutting down before air purification standard has been achieved. 

If a purifier can handle work within a short span of time without malfunctioning, that’s even better. All users will require a purifier with longer life and warranty so that they don’t have to discard that soon in favor of a new one.

Noise

Does air purifier produce a lot of noise while working? Not every individual can withstand every decibel of sounds at all times. Noise, infact, hampers normal concentration of a working individual. the user should make a thorough examination of maximum sound emitted by an air purifier before buying it.

Frequency of filter replacement and Purifier cleaning

How often does a user need to replace filters? How often does the purifier need to be cleaned? Most users will prefer that filters work for a long period of time consistently before their replacement time is due after all user’s money will be saved if the filter happens to be a permanent one. 

If a purifier is made up of good quality material such that it can work efficiently for a long period of time without the user having to undergo hassle to clean it regularly and waste his or her precious time, it would seem a better option.

Portability

Can air purifier be carried from one room to another? If the air purifier is small and lightweight, it’s much easier to place it in any room at any point in time, depending on the requirements of the user. That way, the same purifier singlehandedly sanitizes all rooms within the house.

Remote access or Auto Mode

Can air purifier be controlled from afar? In case the air purifier was rather heavier, or the user was extremely tired to move his or her muscles from the couch yet, he or she needs to switch the purifier off manually, what should he or she do? Wouldn’t it simply solve the issue here if a purifier could be controlled by a remote or cell phone via an app or WIFI? 

Assuming the purifier neither has remote access nor is the user awake enough to switch devices off to conserve energy, this issue can simply be solved if the purifier has automatic sensors for detecting air quality so that it automatically switches on when in need and switches off when air quality seems normal.

Safety

How much quantity of ozone does the ionizer component of air purifier release? How often does a user have to get exposed to UV-C while replacing a lamp, maybe? Are parts too small or sharp in disarrayed condition, unsafe for children? Ozone, as a tropospheric gas, can tend to do more harm than provide safety for users. users should be careful to check that the purifier meets usual standard limits permitted for by-products and not exceed concentration beyond accepted health parameters. 

Ultraviolet radiations are harmful radiation for human beings, especially UV-C types. These may lead to skin cancers and cataracts. Air purifiers are made up of good quality materials that prevent direct contact of users with UV-C To ensure safety. the user needs to bear this thought in mind that children may tamper with the purifier before buying it. Hence he or she needs to choose appropriately.
