Why Our Homes Can Actually Make Asthma Worse
Did you know that more than 300 million people throughout the world suffer from asthma? Or, that an average of 10 Americans die each day (about 4,000 per year) from an asthma-related disease?
What about the fact that the air quality inside our homes is 2-5x worse than outside, according to the U.S. Environmental Protection Agency?
These statistics can sound scary, especially for asthma sufferers, but we assure you that there’s hope right around the corner by using an air purifier.
While no one knows for sure what causes asthma, nor do we have an actual cure for it, we do know some of the reasons why it’s getting worse for people at home.
The major issue is that indoor air quality is in a steady decline.
Many years ago, when houses and buildings were being built, there wasn’t as much focus on making every nook and cranny a super tight seal.
Unfortunately, structural designs have changed and this has created a new problem, especially for people with asthma.
Now, when new houses are constructed, there’s so much emphasis on making them energy efficient for homeowners. That way, we can use as little air conditioning or heating possible while still maintaining a pleasant temperature.
That efficiency is achieved by creating a tight seal throughout every part of the home.
Another issue is that a lot of people don’t like to open their windows anymore. With the number of people who suffer from allergies increasing each year, this makes perfect sense—they’re trying to protect themselves from outdoor allergens.
Now, you may be wondering, “How does a tight seal in my home create problems for my asthma?”
What happens with an airtight seal in your home is that harmful contaminants don’t have a way to freely escape. Once they’ve been tracked inside from the outdoors (through your clothing or by floating in when a door or window is opened) these particles get stuck and can’t get out.
That build up of pollutants results in many homes becoming infested with asthma-inducing particles that continue to cycle in and out of your lungs.
Fortunately, there’s a solution to all of this—adding an asthma air purifier to your home.
What Makes a Room Air Purifier Good for Asthma?
Now that you’re aware of how big of a problem indoor air quality has become, you may be wondering… “How can an air purifier help?”
What makes an air purifier good for asthma is the fact that it strips the air of any particles that cause your symptoms to flare up.
By creating clean, fresh air inside your home, you’ll notice an overall improvement in your health. You’ll be able to breathe easier, get around better, and not have as many sudden asthma attacks.
However, you do need to get a specific type of air purifier if you want it to work properly. Buying the wrong type can actually make your asthma worse.
There are two major types of air purifiers on the market:
- Ionizers (or ionic air purifiers)
- HEPA air purifiers
As an asthmatic, you want to STAY AWAY from ionizers.
These products work by sending out negatively charged ions into the air to neutralize airborne particles, however, studies have shown that these ions can make your asthma worse and may induce asthma attacks.
Also, some ionic air purifiers emit ozone as a by-product which also worsens asthma.
What you WANT for asthma is an air purifier that uses a HEPA filter.
HEPA air purifiers use a highly dense paper filter to collect particles that irritate your asthma.
Once those particles are trapped inside the filter, they cannot recirculate back into the room; this creates the cleanest, freshest air possible for an asthmatic.
Now, the best type of HEPA air purifier for asthma is the “True” HEPA kind.
A True HEPA filter is the only type rated to remove up to 99.97% of particles as small as 0.3 microns in size—standard HEPA filters don’t have this certification and may only capture particles down to 2 microns which is about 500% larger in size.
So if you have asthma, stay safe and look for a True HEPA air purifier (like the ones featured below). It will reduce the highest number of asthma-inducing triggers for you.
Choosing the Right Size Asthma Air Purifier
Another thing you want to ensure when buying an air purifier for asthma is that it can purify a space that’s large enough for your needs.
True HEPA air filters come in a variety of sizes and you need to make sure that you get an air purifier that’s capable of cleaning the room (or several connected rooms) that you want to use it in.
This function is especially important if you suffer from asthma.
For example, if the air purifier you choose can only clean 100 square feet of air, then it won’t do you any good to place it in a room that’s 400 square feet large—the air purifier will fail to clean the air adequately for you.
And not only will this not help with your asthma, but it would be a waste of money to purchase that device.
On the other hand, an air purifier rated to clean a space up to 400 square feet will work great for any room up to this size. This includes 100-400 square feet.
At the end of the day, it’s always best to choose a more powerful air purifier than one that’s inefficient for the space you want to use it in. Having clean, fresh air is crucial to keeping asthma symptoms under control, so be sure to get the right size air purifier.
Now, keep reading below to find out what the best air purifiers are for asthma. We’ve highlighted the top two products that have been designed with the best features an asthma sufferer will need.
The Two Best Air Purifiers for Asthma
Out of all of the air purifiers on the market, this is the best one you can get for controlling asthma.
The reason it’s so good is because it uses a special 6-stage air cleaning process that strips the air from all types of asthma-inducing toxins.
In addition to using a True HEPA filter to capture the finest particles that trigger asthma, you’re also given the option to add an additional layer of protection to this air purifier by choosing between a set of four customized filters:
- Germ Defense
- Toxin Absorber
- Odor Neutralizer
- Pet Allergy Reducer
It holds an Energy Star certification, making it inexpensive to operate, and has enough power to purify an area up to 700 square feet. That makes it perfect for most home applications.
Finally, this device can be wall mounted or set on the floor and the front panel comes in a variety of colors and designs. All-in-all, this combination of high-end features is why it’s ranked as the best air purifier for asthma.
Another great choice for asthmatics is this air purifier right here.
It also uses a True HEPA filter for trapping 99.97% of asthma-inducing particles down to 0.3 microns and has a special verification by the Association of Home Appliance Manufacturers.
Although this air purifier is not wall mountable, it’s small, sleek design allows it to fit practically anywhere inside a room and has a handle for easy portability.
While it’s cheaper than our first recommended asthma air purifier, it does have one drawback—it can only purify an area up to 240 square feet. That’s less than half the size of the Rabbit Air MinusA2 product mentioned above.
However, if you’re only looking to purify a smaller room like a bedroom or just want a dedicated living room air purifier, then this is a great option and will save you a considerable amount of money.
Our final recommendation is for people who have severe asthma or need a device that can handle an extremely large room—up to 1,125 square feet.
This air purifier has an advanced HyperHEPA filter that captures 99.95% of particles down to 0.003 microns—the smallest that exist— and lasts up to four years.
It also includes a special V-5 Cell Gas and Odor filter that removes a wide range of chemical pollutants and household odors.
Additional Tips for Helping with Asthma at Home
While an air purifier is a great way to remove airborne triggers that cause asthma, there are some additional steps you can take to cut down on the presence of these particles inside your home.
Combining these tips with your air purifier can help you get the most relief for your asthma symptoms.
- Vacuum at least once per week. All sorts of particles can be tracked indoors on your clothing and shoes. Therefore, it’s a good idea to vacuum regularly in order to remove these contaminants from the indoor space. Like with air purifiers, you can also get a vacuum cleaner that includes a True HEPA filter. That way it will collect the finest particles possible so they don’t end up in the air you breathe.
- Change your HVAC filters regularly. Home heating and cooling systems use air filters to trap dust, dirt, and hair from damaging the system. The recommended interval for changing these filters is every 3 months, however, if you have severe asthma or allergies then replacing them once per month may be more helpful for you.
- Minimize the presence of smoke. If you have asthma, reducing the use of candles, incense, and wood burning fires can help cut down on smoke particles that can irritate your lungs. Also, preventing the use of tobacco products indoors is also advisable.
- Use your home exhaust fans. You can eliminate a lot of asthma triggers that are kicked up into the air while cooking by turning on the stove exhaust fan. If you don’t have one of these, opening the nearest window can also help. This same advice applies to the bathroom during and after a shower, however, the purpose of the exhaust fan in this location is to extract moisture that can irritate asthma and cut down on the production of mold spores.
- Don’t store paints or chemicals indoors. Although you may have your paints, cleaning chemicals, and pesticides stored inside containers, they can still release volatile organic compounds into the air which can irritate your respiratory system. Therefore, it’s best to keep these products stored outside or in a garage or basement area that’s far away from your breathing area.
- Reduce your exposure to pet allergens. If you have pets, an air purifier can help remove the airborne dander particles that cause asthma and allergies to flare. However, to ensure long-term relief, it’s best to keep your animals out of the rooms where you spend the most time like a bedroom or living room. It’s also a good idea to bathe or change clothes after playing with pets, or at the very least, wash your hands to remove any pet dander particles.
Common Air Purifier Terms and Definitions
When you’re shopping for an air purifier, you’ll undoubtedly come across a number of special terms that relate to the air cleaning technologies. While these words may sound foreign to you, their concepts are not that tough to understand.
Below, are the top terms and definitions you may come across when comparing air purifiers for asthma.
Pre-filter – This is a thin layer of protection that acts as the first line of defense during the air purification process. The pre-filter traps the largest airborne particles as well as dirt and hair. This important function helps to prolong the life of the other internal filters. Most pre-filters last forever and are washable and reusable.
True HEPA Filter – This term was mentioned previously, but in short, it’s the highest standard air filter you can get for an air purifier. To carry the “True” HEPA label, the air filter must meet the strict guidelines of capturing at least 99.97% of particles as small as 0.3 microns. These filters are not permanent and must be replaced when they fill up with too many particles.
BioGS HEPA Filter – Rabbit Air’s special type of True HEPA filter. It’s designed in a way that allows the filter to last up to two years which is much longer than a standard True HEPA filter that needs to be replaced every six to eight months.
HyperHEPA Filter – IQAir’s version of a True HEPA filter. It captures 99.95% of particles down to 0.003 microns which are the smallest that exist; 10X smaller than a virus.
Activated Carbon Filter – This filter is specially designed to remove particles that produce odors inside the home. It works by adsorbing the molecules into the filter medium and trapping them there. Activated Carbon filters are also good for reducing volatile organic compounds which can also trigger asthma symptoms.
V5 Cell Gas & Odor Filter – IQAir’s patented filter that eliminates gas and odors by combining two types of media. The first media adsorbs odors and gases while the second changes the pollutants to an oxidized form. The V in “V5” refers to the V-shaped media chambers that allow for higher airflow than comparable units.
Ionizer – Another term that was mentioned earlier in this guide, but in short, this type of air purifier doesn’t use filters to reduce airborne pollutants. Instead, it emits negatively change ions into the air that latch onto particles to weigh them down. This causes the contaminants to fall out of the air and land in surrounding surfaces. Negative ions can irritate asthma and some ionizers emit ozone as a by-product which also creates problems for asthmatics.
Ultraviolet UV-C Light – This technology kills airborne bacteria and viruses by destroying the DNA structure. Air passes by this light on its way out of the air purifier. It’s not necessarily good or bad for asthma, but it can help sterilize your indoor environment so fewer illnesses are spread.
Air Changes Per Hour (ACH) – A specification that tells you how many times an air purifier can exchange the air inside a room every hour. The higher the number, the more efficient the device is at creating clean, fresh air.
Clean Air Delivery Rate (CADR) – A specification that tells you how well an air purifier can remove certain types of contaminants inside a room (tobacco, dust, and pollen). Only air purifiers that have been independently tested by the Association of Home Appliance Manufacturers (or AHAM) will include CADR numbers.
