  • 3M’s exclusive 3-in-1 technology

    Pollution occurs not just outdoors, but indoors as well. Seemingly harmless activities like cooking and cleaning can release harmful pollutants and toxic particles into the air you breathe.

    Understanding the need for cleaner and healthier air, 3M engineers developed an electrostatic filter that acts like a magnet. It pulls in unwanted particles and traps them, allowing cleaner air to flow through.

Frequently Asked Questions

Get answers to your questions about 3M AC Filters from how it works to how often you should change it to enjoy clean, cool air.

  • How is indoor air quality worse than outdoor air quality?
    Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems in homes. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentrations of some pollutants.
  • For maximum effectiveness, we recommend you apply a new filter every three months. However, the life of the filter can depend on the individual condition of air quality in your home. You can assess physical state of the filter before you decide to change.
  • Actually, it is the average exposure during the day that is most important for your health. The World Health Organisation defines their guidelines for air pollution levels based on the 24-hour average value. By breathing clean healthier air inside, you reduce your daily average exposure level and do the best to protect your health.
  • Washing the filter will reduce the effectiveness of the filter and, is not recommended.
  • No. But in the case of activities involving combustion, removing smoke particles can help reduce the odor.
  • 3M™ Air Conditioner Filter may reduce the need for dusting, but won't eliminate it. Atmospheric dust consists of a wide variety of particulates ranging in size from 0.001 micron to a relatively large 100 microns. Because of the weight of the large particles, they will settle on your furniture long before they could reach your filter.
  • The efficiency of 3M™ Air Conditioner Filter approaches that of the top-of-the-line electronic air cleaners. Some tests indicate that in the large particle size range (1.0-10 microns), 3M™ Air Conditioner Filters are more effective. Price is a factor, too. Top electronic units cost INR10,000 – INR20,000, require maintenance in terms of filter change and also have a running electricity cost associated with them. 3M™ filters cost a fraction of this price, and generally only need attention every three months.
