3M develops AC filters to help combat indoor dust, pollen and allergens

These variants facilitate better air flow through the ACs while trapping airborne particles and delivering cleaner, healthier air

Impure air, in recent times, has come to be amongst one of our most prominent problems and health concerns including respiratory diseases and it is not just about outdoor air. A UN Environment Programme (UNEP) report found that indoor air pollution contributes 22-52% to the overall ambient pollution levels, which multiplies the burden of respiratory diseases.

In an effort to address the situation of poor indoor air quality, 3M has been working extensively to come up with easy-to-use air filtration solutions. After their launch of the first Electrostatic PM2.5 AC filter, a DIY solution for improving indoor air quality, 3M has now launched two even more impactful variants with superior technology. These variants facilitate better air flow through the ACs while trapping airborne particles and delivering cleaner, healthier air. The two variants target specific challenges that users face including pollen, dust mite debris and other allergens, which are prevalent in cities including Bengaluru, Mumbai and others.

The new Household Dust variant of the 3M AC filter can filter upto 90% of PM 2.5 within two hours of use, whereas the Allergen variant, which is certified asthma and allergy-friendly by Allergy Standards (ASL), captures up to 93% in the same amount of time. Both varieties are made with the unique Filtrete brand 3-in-1 technology, which traps unwanted airborne particles, without compromising on cooling. The Household Dust AC filter variant is tough on particles like dust mite debris, mould spores, pollen and household dust, and the Allergen AC filter variant captures a wider range and higher percentage of allergens, which includes these particles as well as pet dander. The asthma & allergy friendly certification by Allergy Standards (ASL) for the Allergen variant of 3M AC filter indicates that the product has been scientifically tested and identified as more suitable for people with asthma and allergies. It has been suggested by various reports that groups including pregnant women, young children and babies, elderly people and those with pulmonological issues like asthma or allergies may be particularly sensitive to the decline in air quality.

Talking about the filters, Sanjit Satapathy, head of Consumer Business Group for 3M India, said, “In the last couple of years, air quality has become a growing concern in India, especially in urban areas. Reports are proving that indoor air can be two to five times worse than the air outside. Furthermore, an increasing number of people are reporting sensitivities to pollen and other airborne particles, particularly during season change. As leaders in innovation, we at 3M believe in applying science to life, to help make everyday life better for everyone. Right now, even more so, there is an increasing concern regarding recirculation of air in crowded places by ACs, which may contribute to the transmission and spread of COVID-19.  Our new AC filters are an ideal option to help improve air quality in Indian homes, offices and clinics which rely on wall-mounted ACs and are backed by our proven track record in meeting the highest international standards of quality and performance.”

Each pack of the new Household Dust and Allergen AC filters contain four filtration sheets that can be easily installed in split ACs as a DIY installation, without any help from a technician or using any tools. The pack also contains two filter change indicators which help the user to understand when their installed filter needs to be replaced for best results in terms of air filtration and air flow.



With the increased concerns related to COVID-19, the company is trying to understand and communicate what individuals can do to help prevent the spread of the virus — and what their products do, in relation to viruses. To be clear, 3M AC filters do not stop the coronavirus, but they do improve indoor air quality. As we practice social distancing and are quarantined indoors, it becomes especially important to maintain a healthier home environment.

Our electrostatic filters improve indoor air quality by pulling in and capturing unwanted airborne particles. These can include viruses, bacteria, mould spores and pollen. It is important to understand the products and their performance in terms of filtration rate, particles captured, and replacement cycle, when selecting the right one for yourself.

Do note that AC filters must be replaced at least every 90 days for optimal performance. After removing the filter, it has to be placed in a bag before disposing and one must be sure to wash their hands thoroughly after disposing.

People are increasingly beginning to understand the importance of caring about the air we breathe. The AC filters are uniquely useful for those who are looking for an affordable solution to manage the air quality at their home or office, and are also readily available for purchase online.
