Frequently Asked Questions About Air Purifiers

According to the Environmental Protection Agency (EPA), indoor pollutant levels may be two to five times higher than they are outdoors and occasionally even 100 times higher! Modern homes are built to be energy efficient that does not let the maintained room temperature, be it heat or cool, to leak out.  This can lead the indoor air to turn stale leading to polluted indoor air. A variety of pollutants can be responsible for indoor air pollution, including pollen, mold, dust, dust mites, pet dander, and smoke of all kinds, to name a few. The EPA also reports that exposure to these indoor air pollutants can result in a wide range of health effects, from immediate to long-term illnesses and mild to severe or even fatal symptoms.

Bonphul Astria range of air purifier is made, specifically for tackling high indoor pollution levels in Indian cities. With four-level filtrations, the Astria models are highly efficient in removing impurities and delivering clean air in your home. Here are few Frequently Asked Questions (FAQs) on Air Purifiers.

Q: What is an air purifier

An air purifier is an appliance that removes certain airborne contaminants from the air and improves the indoor air quality. They are most frequently used in homes and offices and are helpful to people who suffer from allergies, asthma, chemical sensitivity and other respiratory related symptoms. Air purifiers draw polluted air in from a given space and pass it through several layers of filtering devices. Particles, allergens and contaminants are trapped onto a filter and the purified air is then recycled back into the room.

Q. What is the need for an air purifier?

An air purifier will improve the overall indoor air quality and in turn, improve our health. We tend to associate air pollution only with outdoor air; however, the Environmental Protection Agency (EPA) estimates that indoor air pollution levels can be as many as two to five times higher than outdoor pollutant levels.

In fact, indoor air pollution is one of the top environmental concerns. Many of the pollutants removed by air purifiers are known to trigger allergies and asthma; therefore, an air purifier will offer relief to those suffering and lessen the possibility of a person contracting them if they don’t already suffer from them. Infants and small children are especially susceptible to contracting asthma and allergies since they spend the majority of their time indoors.

Q: What is Indoor Air Pollution and how does it affects us?

A: Indoor air pollution is the level of unwanted and harmful particles present in the air indoors. Modern homes are built and sealed to be energy efficient and to hold the air inside. While this is great for reducing your energy bills, it doesn’t allow the home to “breathe.” Pollutants such as pollen, mold, dust, pet dander and tobacco smoke then become trapped and are recirculated indoors instead of being released outside by natural means. This is what causes the Sick Building Syndrome.

Building materials in most newly-built or renovated houses emits Volatile Organic Compounds or VOCs that are harmful vapourised chemicals. VoCs are also emitted by consumer products, like air fresheners, cleaning agents, paints, varnishes, and from copying and printing machines. As we already have high air pollution outdoors, Particulate Matter or PM enters inside and adds to the indoor pollution. Apart from that, kitchen-smoke, fire-places, chemical-infused incense burning, pet danders, mold spores, dust from clothes, upholstery, various microorganisms, human skins, etc. are the major contributors of Indoor Air Pollution. Bad indoor air quality is a full-package of diseases, causing eye, nose & throat irritation, headaches, nausea/vomiting, dizziness, worsening of asthma symptoms, cancer, liver & kidney damage, central nervous system damage to even cancer, and Alzheimer’s.

Q. What are the different types of filters in an air purifier?

A: With a four-level filtration, Astria Air Purifiers addresses the problems of PM10 and PM2.5, harmful gases, and other commonly found pollutants like mold spores, and microorganisms. Here are the different types of filters addressing different aspects of Indoor Air Pollution:

Pre Filters: The pre-filter acts as the first line of defence and removes PM10 pollutants such as dust, smoke, hair, pet dander, large pollens etc. The pre-filter also helps in increasing the life of the secondary filter by not letting it choke sooner.

H11 HEPA Filters: High-Efficiency Particulate Arresting or HEPA filters, are found in a wide range of industries, from residential properties to businesses to medical facilities and more. HEPA filters are highly efficient in collecting microscopic particles in the air as it flows through them. They rapidly hold PM2.5, mold spores and even biologicals.

Activated Carbon Filter: The activated carbon filters come in a granular form that removes contaminants and impurities, using chemical adsorption. They are most effective at removing allergens and harsh pollutants, from chlorine to particulate matters, volatile organic compounds (VOCs), to unpleasant odours. Activated carbon filter provides unparalleled benefits to your respiratory health.

Cold Catalyst Filter: Cold Catalyst filter, is also known as a low-temperature catalyst, formaldehyde buster. Cold Catalyst Filter absorbs, decomposes and removes harmful gases such as formaldehyde, benzene, xylene, toluene, and TVOC, generating water and carbon dioxide.

Q: How much space will an air purifier cover?

A: Air purifiers are designed to fit a variety of spaces, at both your home and office. Make sure you look at the square foot area of the room it will be primarily used in. Bonphul Astria F520 has a CADR (Clean Air Delivery Rate) of 520 m3/h (cubic metre per hour) for 646 sq. ft. area. Considering this, the model ensures a clean zone of a reasonably-sized drawing-cum-dining room at home, or a large-sized conference room or the lobby at the office. Astria W60 model is a compact-sized, wall mounted air purifier for a single room, for around 161 sq. ft. usage, that will cater to your clean air needs inside your own personal space, at a peak speed of CADR (Clean Air Delivery Rate) of 90 m3/h (cubic metre per hour).

Q: Where should the air purifier be placed?

A: An air purifier is advised to be placed in a room or space where you spend the majority of your time in, be it at home or workplace. Most Air Purifiers are for a space that can easily serve a lounge area, like a living and dining area in your house or the office lobby, or conference rooms. For that purpose, Bonphul Astria F520 (floor standing) is the perfect pick. However, if clean air requirement is for a more personal space, like for a bedroom or office cabin than Astria W60 (wall mounted) should be the right choice.

Q: What are the best air purifiers for allergy- and asthma-sufferers?

A: Proper air filtration is crucial for homes of allergy- and asthma-sufferers since allergy and asthma triggers can easily find their way into homes, despite your best attempts. Air purifiers that use HEPA filtration are the best choice for sufferers because they remove up to 99.97% of allergens up to 0.3 microns in size from your environment. Moreover, a combination of pre-filter, a HEPA filter, and a carbon filter together works effectively to clean the air for allergy and asthma sufferers.

However, asthma-sufferers must avoid ionizing air purifiers that emit ozone, which can harm indoor air quality and aggravate asthma and other respiratory problems. None of Astria models has filters that emit ozone.

Q: What air purifiers are best for pet dander?

A: Pet dander (tiny, even microscopic, flecks of skin shed by cats, dogs, rodents, birds and other animals with fur or feathers), is a common household issue if you are having pets at home. Pet dander consists of several allergens that aggravate sensitive immune systems, including pet saliva, dead skin cells, and even outside particulates brought in by your pet on their coat. These factors or allergens trigger those allergies and, more often than not, are dispersed throughout your indoor air and on furniture.

Both the Astria models contain HEPA filters, which is essential for trapping pet dander particulates and eliminating odours through their unique stage filtration.

Q: What does CADR stand for?

A: CADR stands for Clean Air Delivery Rate. This measurement was developed by the Association of Home Appliance Manufacturers. It indicates the volume of filtered air delivered by an air purifier. It is given in three measurements – one for pollen, one for tobacco smoke, and one for dust. The higher the CADR number, the faster the unit filters the air.

Q: What is a micron?

A: Short for micrometre, a micron is one-millionth of a meter and approximately 1/25,000th of an inch. Microns are used to measure airborne particle sizes. This is important because many harmful airborne particles are invisible to the naked eye, making them easily inhaled or distributed throughout your indoor environment. For example, dust mite allergens can be as small as 0.1 to 0.3 microns, which is considerably smaller than a single strand of human hair that typically measures 30 to 120 microns.

Q: Are the air purifiers loud?

A: The loudness of an air purifier (measured in decibels) depends on a few factors such as the model of air purifier, the fan operating speed, and personal noise tolerance. Astria F520 and Astria W60 have noises of 58 dB(A) and 50 dB (A) respectively. However, like most air purifiers, Astria models too feature multiple cleaning speeds. Thus, if they are operating at their maximum cleaning speed, it will be louder than if they are operating at a lower speed. Also, noise is subjective and what might be intolerable to one might not be as loud to another.

Q: How long should I run my air purifier?

A: For best results, it is recommended to continuously run your air purifier. To help with noise and electricity costs, most air purifiers come with multiple cleaning speeds. For example, to maintain your indoor air quality while you are away from home, your air purifier can be on a lower setting than when you are home. This saves energy and cuts costs while still maintaining a clean environment.
