How Air Purifiers Works at home


The air purifier for dust is an electronic device for the elimination of contaminants, smoke, microbes and allergens from the rooms in your home. It enhances the air quality and makes it hygienic for breathing. People suffering from lungs, heart, and nasal canal disorders get protection from allergies and infections. Here, we introduce to the important concepts of how air purifiers work at home.  

Air Purifier for Dust-Types

Air Purifier works on the various technologies of polarized media, UV irradiation, thermodynamic sterilization, ionizer, or through ozone generation. The latest technology system uses the filtering method for filtering the micro and nano-sized particles from the air.

Air Purifier- Components

The new system works with the help of various filters, cartridges, grills, pre-filters and a powerful motor. Air passes into the purifier, gets cleaned and passes out through the outlet. The frequency of air transfer into and out-of-the purifier determines its efficiency and speed. It is largely decided by the motor speed and capacity.

Air Purifier-Pre Filter

Pre-filters are used for the removal of macro-sized particles like dust, dirt, pet dander, pollen, etc. using multiple pre-filters. These help in removing up to 99.95% of the pollutants before the air passes into the main filters. Pre-filters are generally made of foam and a metal mesh and have micron-sized pores. Removal of odor and harmful gases from the air is the other task performed by the pre-filters.

Air Purifier- Microbial Filter

The microbial filter eliminates different types of harmful bacteria, allergens, and other microbes in the air. It is considered to be the most important part of the purifier. Advanced systems may have multiple layers of filters to filter out the nano-sized microbes completely.

Air Purifier- HEPA Filter

High-Efficiency Particulate Arresting system filter out almost all types of airborne contaminants of size 0.01 µm. It traps all the particles within its fold and allows clean air to pass through its outlet.

HEPA filter provides a large coverage area with high-speed cleaning facility. For example, you may choose a system with the capacity of 150-160 Square-feet in 30 minutes or less for your living room, drawing room, and guest rooms.  At the same time, they scale down their operational capacity to match with the smaller rooms in your home. An efficient air purifier uses multiple HEPA filters for enhancing its working speed, capacity, and efficiency.

Air Purifier- Activated-Carbon Filter

Activated carbon is the coconut charcoal which has µm sized pores. The layer is highly energized with antimicrobial properties and air purification filters. On an average, one-mm of activated carbon eliminate the odor and smoke at the rate of 150-160 Square-feet per 30 minutes or higher, depending on the air purifier capacity.

Activated carbon also eliminates the harmful ions from the air and inject it with the charged anions. Breathing such air enhances the health and fitness levels of the lungs and nasal canals. Removal of carbon compounds from the air makes it highly hygienic and healthy for breathing.

Air Purifier– Cartridge

Air passing through the cartridge is injected with a pleasant fragrance. Advanced air purifiers use natural plant-based aromatic elements for creating liveliness within the air that you breathe. Most of the purifiers have replaceable cartridges with different fragrances.

Air Purifier- Motor  

The motor is the core component of the air purifier. It extracts air from the surroundings and pushes it through the pre-filters at high pressure. An efficient motor rotates at high speeds to capture and clean the air consistently.

Air Purifier for Dust– Efficiency

Apart from removing contaminants and microbes, an efficient air purifier for dust eliminates the volatile chemicals from the air.  Most of them are dissolved in the air and highly complex for filtering. If you choose a purifier which can capture 0.01 µm size particulates, it is considered to be highly effective and practically applicable for your home needs.

An efficient air purifier also kills the mold on the walls, ceilings and other narrow spaces in your home. The task is mainly performed by the HEPA filter in the system.  

Air Purifier- UV Irradiation

UV irradiation of air eliminates up to 99.99% of microbes and infection-causing bacteria. There is a widespread fear that UV could cause health issues in your home. However, the advanced filters use the UV irradiation units within their closely protected units. Hence, the probability of UV radiations entering your room is nearly zero.

Air Purifier- Ion Exchange

Air purifiers for the densely fogged environment work at the maximum efficiency through the ion exchange process. The system can be integrated into the standard apparatus. It injects freshness into the air by removing the humidity and heat during summer and eliminating dryness during winter.

The air purifier works efficiently with the help of an electronic panel for controlling the speed, filter options and frequency of air cleaning. An automated system detects the changes in the exterior air conditions and change the operational parameters accordingly.

Once you are familiar with how air purifiers works at home, it becomes easy for you to choose the right model and size according to your needs.
