Common Allergy Triggers in Your Home

It might come as a surprise to most people but very often the things that cause allergies are present in the house. Three of the most common of these triggers are dust mites, mold, and pet dander.

Dust Mites

Dust mites are those residents of every household that no one is aware of. The reason for this is that dust mites are very, very tiny. In fact, they are microscopic. Although they themselves are harmless, their waste and bodies can pose a problem.


Mold is usually found in dark, musty, and damp places. However, the spores that it produces can mix and spread through the air. These spores, when inhaled, can trigger allergies.

Pet Dander

Pet dander is basically the small flakes of skin that your pet sheds. These are although very small, but they can trigger allergies when inhaled.

How to Choose Air Purifier for Allergies?

When you are looking for an air purifier, there are some things that you need to keep in mind. Air purifiers made specifically for allergies are a bit different than regular air purifiers. Factors to consider include:

HEPA Air Purifier

HEPA also known as High-Efficiency Particulate Air Filters is one feature that you should definitely look for in any air purifier. These filters can filter out contaminants from the air up to 99.7%. Moreover, they capture particles that are as small as 0.003 microns.

Carbon Filters

These help filter out the air and make it more breathable. They treat the air by removing odors caused by smoke, mold, pet dander, and more.

Ionic Air Purifier

This type of air purifier does not use paper filters like the rest. An ionic air purifier emits charged particles that latch on to contaminants and remove them from the air.


The power of an air purifier is another important feature that needs to be considered. Any purifier that you chose should be able to purify the area it is installed in.

Our Review

Made by a company based in South Korea, this air purifier brings some unique features to the market. Like any other purifier, it comes equipped with a carbon filter and a HEPA filter. However, it has some extra layers that are not found in your everyday variety. The carbon filter is placed behind a micro mesh layer.

This layer is made from metal and its job is to trap the larger particles. This includes dust, pet hair, etc. After this, the carbon filter and HEPA filter perform their respective functions, ridding the air of odors and the smallest contaminants. Lastly, the purified air passes through an ionizer.

The Coway AP-1512HH Mighty Air Purifier is built with a total of five settings. This includes three fan speed settings, an eco-mode, and an automatic mode. The purifier also comes equipped with a sensor. When in automatic mode, this sensor helps identify the contamination level in the air and adjusts the settings accordingly.

Moreover, if the purifier is set to automatic mode and it does not sense any contamination for 30 minutes, it will shift to eco-mode. On eco-mode, it will shut down until it senses contamination in the air again.

The air purifier also comes equipped with a light indicator. This indicates the pollution level in the air. It uses the colors blue, purple, and red to display clean, moderately clean, and dirty air respectively.

Bottom Line

This air purifier, although small, can easily treat a large space. Moreover, automatic and eco-mode both make the purifier very easy to use. In addition to that, the noise emitted from this purifier is very subtle. Therefore, it does not cause much disturbance either. All in all, this purifier is well-rounded and is a good choice.

The HPA100 also reduces the use of energy. However, this does not affect the power of the output in any way. Instead, it only helps you save cash on your utility bills.

The controls of this purifier are also very easy to use. Moreover, the purifier also has a built-in timer which functions in two, four, and eight-hour intervals. The HPA100 can also recirculate fresh air up to five times in an hour.

The Air MinusA2 has quite a modern look. It is made mostly of metal and is crafted in a sleek square shape. It has an LED panel in the middle which shows if the purifier is on or off. A panel on the right side of the purifier holds all the control buttons of the device.

Our Review

The GermGuardian AC4285 is a portable air purifier that works wonders. It has a three-step purification system. The first step comprises a pre-filter with activated carbon. It stops the larger particles from going through as they could clog the next filter.

Bottom Line

If you are looking for a small, yet effective air purifier, this is the one for you. Not only does it work efficiently, but the UV-C technology is a big plus for anyone looking for a good purifier that deals with allergens.
