Specifications for Air Filters

 

Filters are an integral part of an air purifier because they are tasked with the cleaning process of the air. Their way of operation is by physically eliminating the sizeable airborne particles. So the efficiency of an air purifier purely relies on the type and quality of its filters.

Another reason as to why filters cannot be overlooked in purchasing an air purifier is because the long term costs of the product are highly dependent on them. Filters are the only components of an air purifier that requires periodic replacements. Therefore, 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 highly equipped with interlocked fibers that physically eliminates particle pollutants from the air. This type of filters has the ability to filter out at least 99% of the 0.3-micrometer particles from the air. HEPA filters demand frequent cleaning and occasional requirements, which especially multiply in number if you live in dusty environments.

Carbon Filters

This type of air filter is inclined to providing clean air by adsorbing volatile chemicals. The adsorption process has to reach an equilibrium, something that frustrates the cleaning process as then the process of adsorption has to get to the equilibrium level for it to effectively remove all the pollutants. Otherwise, carbon filters clean the air by converting the gaseous contaminants in it to their solid states.

Some air purifiers feature compound filters that combine their form in three or two in one while others just have multiple filters. It is upon you to determine what works for you at your budget and air cleaning efficiency needs.

Types of Air Purifier Technology

In our article on the best air purifier for your living room, we highlighted the various common types of technologies used in air purifiers. We also discussed the different filters used to clean in air purifiers. In this article, you will be going through some other unique air purifier technologies not mentioned in the other article in this section. Here are a few examples of air purifier technologies you may not be aware of:

Photo-catalytic Oxidation (PCO)

This kind of air purifier technology is very new in the market. Besides preventing the entry of unconditioned air into a building space it also provides good air quality benefits 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 tiny (nano) particles of Titanium Oxide to jointly neutralize the adsorbed acidic gases. The decomposition of pollutant particles begins from the surface by a process called photo-catalysis.

Cell Technology

A bioreactor cell attracts charged pollutant particles to rid the microscopic contaminants present in the air, and it also starts an enzymatic action that makes the pollutants harmless. This way they become less reactive and should not worry you if these particles find a way into your ducts.

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 about 200- degree 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 generally a type of photo-catalytic oxidation technology. The process entails 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

Aside from the type of filters, there are so many other factors that must be considered when purchasing an air purifier for the bedroom. The air filter is typically mentioned as a large determining factor because this is an area where the efficiency of the purifier lies.

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

These include:

Noise Level

This is especially of critical importance in the bedroom because you deserve a silent night plenty of rest. Unlike the living room, you will need a purifier with 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.

Similarly, bedrooms are naturally smaller than the living rooms, with an area of less than 400 sq. ft. So your bedroom is fine with an air purifier that has a CADR value of less than 350.

Design Parameters

This can be broken down to the size and weight of the air purifier. Lightweight designs can be shifted from one room to another easily but are less effective in air cleaning. Cumbersome models, on the other hand, are so bulky to carry around but have a great impact on the air around. Recent models have been able to adopt a system which 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 personally insist you interpret the architectural drawings of your building so as to determine the accurate measurement of area. You then should convert the area obtained to square feet before moving on to read from different models to ascertain a figure that’s compatible with the area coverage you require.

Initial & Lifecycle Costs

The first other things that ring in the mind when buying anything is the initial price it costs to buy it. Sequentially followed by the 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 original budget. Changing the air filters is a simple DIY operation that will take you less than five minutes.
