What You Need To Know About Dust Mites
Dust mites are not dust. They are microscopic bugs that escaped the human eyes. A single dust mite measures about 0.3 millimeters. Unless you are using a microscope, dust mites are pretty invisible.
Dust mites feed on dead skin cells, and they grow rapidly in a warm and humid environment. If you spot molds and mildews growing in the bathroom, chances are, your home is an ideal spot for dust mites. In fact, the question is not about whether dust mites exist in your home, but if the numbers are sufficient to pose problems to health.
There are a few spots that are the common breeding spots for dust mites with the mattress being the favorite. When you spend 8 hours sleeping on the bed and shedding of skin cells, you’re practically giving the dust mites to an unlimited supply of food.
Other usual suspects location for dust mites are cushions, rugs, mattress, curtains, furniture and dark corners of your home littered with dust.
Most of us would have thought that dust mites are the culprit of the allergic but it is their excretion that are triggering the symptoms in our body. Dust mites produce fecal pellets that contain a type of protein that causes allergy.
To stop dust mites allergy, not only you’ll have to get rid of the dust mites, but also their excretion as well. And this brought us to the air purifier.
What Is HEPA Filter
HEPA filter seems to be the buzzword in today’s appliances, including air purifier. HEPA stands for High Efficiency Particulate Air and is a standard defined on the air efficiency.
A HEPA filter is made with fiber sheets that are designed to block 99.97% of particles as small as 0.3 microns. This means a HEPA filter can block allergens like danders, pet hairs, dust mites, and other harmful particles of that size.
Today, you’ll find that the word HEPA filter is used unsparingly as a marketing advantage. For example, some brands use True HEPA to differentiate their products.
What’s important is the filter is compliance to the HEPA standards, which means blocking 99.97% of 0.3 microns particles. Avoid ‘HEPA-like’ filters as they are not tested against the HEPA standard.
How Air Purifier Works
Air purifier, with its sophisticated design and array of glowing lights, can seem pretty complicated. But today’s modern air purifier is based on the concept of the protective masks for firemen. Its ultimate objective is to prevent pollutants from being inhaled into our respiratory system.
The air purifier functions by channeling the airflow through a series of filters to remove allergens, dust, bacterias, smoke, pet dander and other pollutants. The clean air is then directed back to the room. By leaving the air purifier on, the air quality of the room improves over time.
There are two types of parameters that define the capacity and efficiency of an air purifier. The clean air delivery rate (CADR) indicates the rate that the air purifier filters out polluted air. It is expressed in cubic feet per minute.
The AHAM (Association of Home Appliance Manufacturers) ratings specify the maximum size of the room that the air purifier is designed to operate in. These two ratings will give you a good idea if a particular air purifier is suitable for your room.
Common Types Of Air Purifier
There are 5 types of air purifier that modern technology has produced.
1. HEPA Filter Air Purifier
The HEPA air purifier is arguably the most effective in terms of filtering out pollutants. It is based on the HEPA (High-Efficiency Particulate Air) technology. The air purifier is fitted with a HEPA filter, which is designed to meet the standards set by the DOE.
Any HEPA filter is rated to remove 99.97% of particles of no smaller than 0.3 um from the air. It is the exact technology that is being used in hospitals to remove contaminants from the air. The HEPA filter has a fiber-like construct that removes pollutants through 3 methods; interception, impaction, and diffusion.
In an air purifier, a HEPA filter will last for at least 2 years or more, depending on the frequency of the usage.
2. Activated Carbon Air Purifier
Activated carbon is an extremely porous form of carbon that is highly efficient in absorbing chemical-based pollutants. The carbon is usually available in powder or block form and reacts and remove harmful compounds from the air.
While it is effective to remove odor and other chemical irritants, activated carbon works best when paired with HEPA filters.
3. UV Lights Air Purifier
Ultraviolet lights are known to kill germs and bacterias. An air purifier equipped with UV light does so by drawing the contaminants to the filter that is exposed to UV light. One of the drawbacks with UV light is the process of exterminating the contaminants also produce ozone, which can be hazardous in high amount.
Of course, advanced UV light technology applied by some manufacturers produce a very small amount of ozone.
4. Negative Ion Air Purifier
An ion is a particle that is neutral in charge. A negative ion is one that has acquired an additional electron to make it negative. An air purifier that is driven by this technology releases negatively charged particles into the air. The negative ions will attach itself to the pollutants before dropping off to the floor or sticking on the wall.
The disadvantage of the negative ion air purifier is that the contaminants are not really removed but scattered around in the area. There’s also a risk of a high level of ozone being produced in inferior quality of purifiers.
5. Ozone Air Purifier
Ozone is the name given to the integration of 3 oxygen molecule. It is highly unstable and reactive with any allergen, or contaminant it comes into contact. While this seems like an effective approach in purifying the air, ozone also reacts destructively with our body.
Exposure to ozone can lead to choric respiratory issues, including breathing difficulty, asthma and damaging the airways. Ozone air purifiers have been banned by California for home users, due to its negative implications.
Why Get A HEPA Air Purifier For Dust Mites Control?
This is one of the most important questions you should ask before getting an air purifier. The answer lies in the type of air purifier you’re using and the expectation of what the air purifier can do. A HEPA air purifier can effectively remove dust mites from the air within its effective coverage.
As mentioned, the air purifier is equipped with a HEPA filter that will trap 99.97% of allergen including dust mites and its excretion. However, this does not mean that an air purifier can remove dust mites that are deeply entrenched in the mattress.
With that said, having a HEPA air purifier in the bedroom helps to remove dust mites that are sent to the air when you are making the bed. It minimizes the amount of dust mites feces that are inhaled, and thus reducing allergic symptoms.
Studies have also indicated the effectiveness of the HEPA filter in minimizing allergens, such as dust mites.
