Minimize your Asthma Symptoms with an Air Purifier

Asthma is a horrible breathing condition that affects millions of people all over the country. Not only are the symptoms incredibly uncomfortable, but they can also be potentially very dangerous. It is because of this that it is so important that you do whatever you can to lessen the discomfort of asthma symptoms if you, or anyone else in your home, suffers with asthma.

One of the easiest ways to minimize the symptoms of asthma when you are at home is to invest in an air purifier. Air purifiers work by absorbing and trapping airborne pollutants and allergens in their filters, thus giving you much cleaner air to breathe. Here are a couple of the benefits of using an air purifier in your home:

  • Remove Dust – One of the biggest things that aggravate asthma symptoms around the home is dust. Even if you try and remove as much of it as possible through daily cleaning, there will always be dust particles circulating in the air. These particles are invisible to the
  •  naked eye but can cause havoc for an asthma sufferer. By using an air purifier you can drastically reduce the amount of dust in the air.
  • Improve Air Circulation – Another benefit that you get with an air purifier is that it is able to drastically improve air circulation around the home. As you can imagine, air that doesn’t circulate properly can affect an asthma sufferer in a very negative way.
  • Filters Large Particles – Things such as pet hair, pollen spores and mold spores can often circulate around the air in the home. As with other allergens, these cannot always be seen, but their effects can certainly be felt by an asthma sufferer. By getting an air purifier with a pre-filter, you will be able to trap these large particles and remove them from the air.
  • Remove Mold Spores – Mold spores can often be found circulating around the air in the home without us even being aware. These can affect all of us, even those who don’t have pre-existing medical conditions. By using an air purifier, you are able to remove the mold spores in the air completely, thus reducing any risk of illness.

Choosing your Air Purifier

When it comes to choosing an air purifier for asthma sufferers, it is important that you consider a number of features to make sure that you get the best results possible. Here are a couple of the biggest features to keep in mind.

  • Filter Type – When you are choosing your air purifier, one of the first things that you should be looking at is the filter type that it uses. For an asthma sufferer, you should ideally look for a unit that has a pre-filter, a HEPA filter and an activated carbon filter, or a combination of at least two of them. This will pull the maximum amount of allergens from the air as well as trap the larger particles.
  • Noise Level – If you are going to be using an air purifier for the purpose of alleviating asthma symptoms, then it is likely that you are going to be running it overnight. If this is the case, then the noise level of the unit is going to be an important factor to consider. You want one that is quiet enough to not disturb you whilst you are asleep.
  • Fan Speeds – If you are an asthma sufferer then it is likely that your symptoms will vary at different times of the year. For example, they may be worse during the summer months because of a high pollen count. It is because of this that you should look for an air purifier with adjustable fan speeds. This will allow you to change the amount of allergens removed when necessary.

There are a number of other features that should factor into your buying decision, but these are among some of the most important. If you have no idea where to start, then we are here to help. We have tried and tested a number of air purifiers so that we can review them for you. Below you will find our top 3 air purifiers for asthma sufferers.

3. INTEY HEPA Air Purifier

To start off with, let’s talk about the set up and installation of this INTEY HEPA air purifier. The unit itself came very well packaged and it was simply a matter of plugging it in to get it up and running. When selecting the functions, there are 4 options, a button for resetting the filter, a button to select the speed, a button to switch negative ions on and off and a button to switch the nightlight on or off.

What we liked about the buttons is that they are very user friendly. You can clearly see what you need to press in order to change the various settings. The first thing that we were really impressed with is the fact that there are 5 different speeds. Usually with an air purifier in this price range you will get 3 speeds maximum, so this is a plus point.

The fact that it releases negative ions is another big plus. This produces much cleaner air all around. The nightlight feature is a welcome addition as it is good for using overnight along with the lowest speed which produces the lowest amount of noise so it doesn’t interrupt sleep.

The main thing that we really liked about this particular air purifier is the fact that it has 3 different filters; a fine preliminary filter for trapping larger particles, a HEPA filter for trapping pollen, dust and other allergens, and an activated carbon filter for removing odors from the home. We found that this 3 stage filter allowed us to get much cleaner air after just a few uses.

Overall, this is a great mid-range air purifier that is very effective even after only a couple of uses.

  • 56dB Noise Level
  • 5 Speeds
  • Preliminary Filter

2. Vax AP01 Air Purifier

Much like the previous air filter on our list, we were pleased with the ease of setting up this one. It is simply a matter of plugging it into a power source and then we are ready to go. Upon starting it up, we were presented with two lights which indicate when the filters need to be changed and 4 different touch control buttons. The buttons allow you to change the speed and the timer function as well as power the unit off or on and reset the filter.

We have absolutely no complaints about the ease of use of the touch controls. They couldn’t be simpler, which is just what you want. We tested out all three speed settings. The only complaint that we could possibly note is that the unit can be quite noisy at the highest speed setting, so if you are going to be using the unit overnight then it is definitely a good idea to keep it on the lowest speed.

One thing that we definitely liked about this one was the timer setting. With this, you can set it so that it shuts itself off after a certain amount of time. This is very beneficial if you plan to use the air purifier overnight to combat asthma symptoms. It will not only save you electricity, but also save you from hearing the noise for longer than necessary.

This particular air purifier has two filters; a HEPA filter and an activated carbon filter. After the first couple of uses we noticed that the HEPA filter especially had collected quite an impressive amount of dust and dirt. We certainly felt the difference in the air after using it overnight.

When it comes to the design of this air filter, the one thing that we like is that it is quite slim. It could be easily placed against a wall and be mistaken for a portable radiator. It has been well designed and feels like it has been built to last, which you would definitely expect from a brand like Vax. It feels surprisingly lightweight considering it is rather large, so it could be easily moved between rooms if necessary.

For the price of this air purifier you really cannot go wrong. It is highly effective and powerful enough to completely clean the air of a large room. Highly recommended.

  • 3 Speeds

1.     Levoit Air Purifier – Our Top Pick

Out of all of the air purifiers that we reviewed, this one from Levoit takes the top spot. First of all, we liked the unique design of this one. It is cylindrical inLevoit Air Purifier shape which is a little different from the norm. This is a really compact model but it certainly packs a punch in terms of power. Setting up the unit is relatively easy; it is simply a matter of fitting the filter and plugging the unit in.

In terms of style, we liked the modern look of this one. It could easily be placed on a bedside cabinet or a side unit and it wouldn’t look out of place. Now, onto the features. This particular air purifier has three different settings, a low setting for use overnight, a medium setting for daytime use and then a high setting for use in conditions where the pollen count is high or there are more allergens than usual. Choosing the function that we wanted was easy to do and we had no problems with the controls, they are very user friendly.

One thing that we really liked about the controls is that they are touch sensitive. It couldn’t be easier to change the settings; it is just a matter of brushing your finger over the required button. Another thing that we liked about this one is the built in nightlight. This can be dimmed or completely switched off, depending on your preference.

After using the unit for a couple of hours we certainly noticed a drastic difference in the removal of unpleasant odors lingering. It completely eliminated pet odor and tobacco smoke, leaving the air feeling crisp and clean. Within a couple of days of continuous use, the air purifier had collected a substantial amount of dust on the filter, proving how much power it has.

For a very reasonable price, this air purifier is a definite winner. It is touch controlled, well-designed and highly efficient. This is why the Levoit Air Purifier is our top pick for asthma sufferers.
