Air Purifiers: Are They Worth the Cost or Not?

Air purifiers have become popular in recent years as people strive to improve the quality of the air they breathe. The demand for these devices has rocketed during the pandemic as a way of adding protection against COVID-19. These are also popular in large cities where air pollution is a major problem.

What Are Air Purifiers and How Do They Work?

Air purifiers remove dust, pollen, mould, smoke and other airborne particles from the air. They also help to reduce the spread of airborne diseases by removing these contaminants from the air.

There are several reasons why people are choosing to buy air purifiers:

1. Mitigates Air Pollution

Air pollution is a major health hazard. It has been linked to a range of health problems, including respiratory infections, heart disease and cancer. A purifier filter captures air pollutants that can do damage to the body.

2. Improves Indoor Air Quality

An air purifier can help improve your indoor air quality and reduce your exposure to potentially dangerous particles. This can be a cost-effective way to improve your indoor air quality. 

3. Reduces Allergies

If you suffer from allergies or asthma, an air filter can help to remove allergens and irritants from the air, making it easier for you to breathe.

Are Air Purifiers Worth the Cost?

One of the most important aspects of a purifier that also determines its cost is the air filters. Filters are what remove the airborne contaminants from the air, so it is vital that they be effective. 

There are a variety of different types of air filters available on the market, and each has its strengths and weaknesses. The type of filter you choose will depend on your specific needs and preferences.

Types of Air Purifier Filters

HEPA Filter

HEPA air purifiers are considered to be the gold standard when it comes to air filtration. HEPA stands for high-efficiency particulate air. These air filters for home can remove up to 99.97% of particles that are 0.3 microns or larger from the air. HEPA filters are very effective, but they can also be quite expensive.

Activated Carbon Filter

The next most common type of air filter is the activated carbon filter, which uses a chemical process to remove contaminants from the air. Activated carbon filters are often more expensive than mechanical filters, but they can be more effective at removing certain types of pollutants, especially those that emit bad smells.

Ultraviolet Light Filter

The last type of air filter for home is the ultraviolet (UV) light filter, which uses ultraviolet light to kill bacteria and viruses. 

There is no one-size-fits-all answer when it comes to choosing air filters for home so it is important to consider your specific needs and preferences before making a decision.
