Air Purifiers for Asthma: A Buyers Guide

Along with a few technologies, the different types of air purifiers for asthma include high-efficiency particulate air filters or HEPA, electrostatic precipitators and activated carbon filters. Given below are the advantages and disadvantages associated with each type.

High-Efficiency Particulate Air Filters or HEPA

The most common type of air purifier, these filters can capture from as low as 0.3 microns to as high as 1-micron particles in the air. Some of the best models come with a pre-filter that removes larger contaminants such as dust and hair earlier. A HEPA filter has the ability to purify air sufficiently for asthma patients.

Electrostatic Precipitators

Ensuring that they are always plugged in, these filters have a good capacity for removing airborne pollen, dust mites and mold spores from the environment. The working process involves the ionization of pollutants which aids in collecting particles from the air. The filter requires changing after a certain time period but they are effective in removing allergens from the air that help you breathe easier.

Activated Carbon Filters

Though these filters can be a little pricey, they have been designed to remove gases and airborne chemicals from your environment including smoke, scents and fumes resulting in improved breathing. However, they need to be replaced every six months and cannot be used in the presence of a smoker.

Before making a purchase decision, you should keep these points in mind while looking for the best air purifier for asthma.

  • Types of filters: It is important that you buy an air purifier for asthma depending on the type of pollutants in your surrounding. For instance, if you are living with smokers or pets at home, it is recommended to buy an air purifier with an activated carbon filter. If pollen and dust are your major concerns, opt for an air purifier having HEPA filters that remove particulate matter from the air.
  •  Filtration Capability: The filtration capability of an air purifier for asthma is measured by its CADR (Clean Air Delivery Rate). You can compare this value before making a purchase decision. It’s important that you buy an air purifier with a high CADR rating as it ensures the efficient removal of contaminants from the air.
  •  Pricing: It is important that you check out various types of air purifiers for asthma before buying one depending on your budget.
