Specifications for Air Filters

Filters are an integral part of an air purifier because they filter out the bad air particles. They operate by physically eliminating the sizeable airborne particles. So the efficiency of an air purifier relies on the type and quality of its filters.

Filters are the only components of an air purifier that requires periodic replacement. Therefore, the durability and lifecycle costs of the filters should be your two key priorities when purchasing an air purifier.

Here are a few types of air filters available:

HEPA Filters

The high-efficiency particulate air filter (HEPA) is the first type you should look for.

HEPA is equipped with interlocked fibers that physically eliminate particle pollutants from the air.

This type of filter has the ability to filter out at least 99% of the 0.3-micrometer particles from the air. HEPA filters demand regular cleaning, with increasing frequency if you live in dusty environments.

Carbon Filters

This type of air filter works by providing clean air by adsorbing volatile chemicals. The carbon filters clean the air by converting the gaseous contaminants in it to their solid states.

Some air purifiers feature compound filters that combine many filters in one, while others just have multiple filters. It is up to you to determine what works for you at your budget and meets air cleaning efficiency needs.

Types of Air Purifier Technology

Here are a few examples of air purifier technologies you may not be aware of:

Photo-catalytic Oxidation (PCO)

This air purifier technology is new in the market.

Besides preventing the entry of unconditioned air into a building space, it also improves good air quality indoors.

The ability to oxidize and destroy organic contaminants is what makes photo-catalytic oxidation powerful in cleaning your air.

Titanium dioxide (TiO2) Technology

Calcium carbonate blends with nanoparticles of titanium oxide to jointly neutralize the adsorbed acidic gases. The decomposition of pollutant particles begin from the surface by a process called photo-catalysis.

Cell Technology

A bioreactor cell attracts charged pollutant particles to get rid of the microscopic contaminants present in the air. It also starts an enzymatic action that makes the pollutants harmless.

Thermodynamic Sterilization

This system adopts heat sterilization through a ceramic core to kill germs (viruses, allergens, bacteria, fungi, molds, and the likes). Air is heated up to 200- degrees centigrade and then passed through heat transfer plates for cooling and let out.

Thermodynamic sterilization neither filters out nor traps pollutant particles. This process only ensures the disease-causing microorganisms in the contaminants have been dealt with.

Photo-electrochemical oxidation

This is a type of photocatalytic oxidation technology. The process uses catalyst materials and reactive species interacting in an electrochemical process to boost the quantum efficiency.

With better quantum efficiency, it becomes easy to adopt a light source with less UVA radiation energy and still achieve maximum efficiency.

Buyers Guide

Apart from the type of filters, there are many other factors that must be considered when purchasing an air purifier for the bedroom.

The different filtration and cleaning system dictates the ability of the purifier to effectively purify the target area. There are several other factors to consider when purchasing an air purifier for your bedroom.

These include:

Noise Level

This is of critical importance in the bedroom because you deserve a silent night and peaceful rest. Unlike the living room, you will need a purifier with a lower Clean Air Delivery Rate (CADR).

In other words, you will need a machine that cleans the air in your bedroom at a slower rate as compared to the one you need for your living room.

Design Parameters

This can be broken down to the size and weight of the air purifier.

Lightweight purifiers can be shifted from one room to another easily but are less effective in air cleaning. Heavier models, on the other hand, are bulky to carry around but have a great impact on the air around.

Recent models have been able to adopt a system that combines the functionalities of an air purifier and a fan. And that’s aimed at achieving both lightweight and efficient models.

Size of the room

You have to be exact and precise when it comes to picking the right purifier for the size of your room.

Experts advise that you interpret the architectural drawings of your building so as to determine the accurate measurement of the area. With that information, you can calculate the volume of the room and find a purifier that meets the requirement.

Initial & Lifecycle Costs

Apart from the buying cost, there will be a certain amount that will be spent on repairs and maintenance during the life of the product.

It is important to check these types of costs to ensure they fall within your budget. Changing the air filters is a simple DIY operation that will take you less than five minutes.
