Air purifier

Millions of people across the globe suffer from one of three types of asthma. In general, asthma is recognized as a long term condition that affects a person’s airways. This results in inflammation in the lungs, which can then restrict the supply of air. Individuals who have asthma may experience wheezing, coughing, breathlessness, tightening of the chest, and an increase of mucus production.

Asthma attacks often occur when symptoms become severe. These attacks can happen suddenly and can range from something mild to a life-threatening one. In some instances, swelling in the airways can then prevent the lungs from receiving an ample supply of oxygen. When this occurs, the bloodstream and vital organs are deprived of oxygen. Individuals who therefore experience these extreme symptoms will require immediate medical attention. A physician can prescribe suitable medication and treatments in order to best manage their symptoms.

To understand asthma, it is vital to understand the breathing process. Whenever we take a breath, the air we take in goes through the nose and then down to the throat into the airways and then finally to the lungs. From there, oxygen is delivered to the bloodstream from countless small air pathways. The symptoms of asthma manifest itself when the muscles and the linings of the airway tighten and swell. The airways are then filled with mucus which further restricts the amount of air that can pass through it. This then leads to conditions that are typical of an asthma attack.

Factors To Consider When Buying The Best Air Purifier For Asthma

A Woman who is choosing a Air Purifier For Asthma

Air cleaners are the best tools that can help clean and purify air indoors, which can become polluted and fill up with particles like dust and pollen which can then trigger asthma symptoms.

The use of purifiers also helps sustain an environment that is healthy by eliminating the growth of mold spores, the presence of pet dander, and any possible asthma allergens. That said there are certain things to put into consideration before buying an air purifier.

With so many options available, it does pay to look into the following qualifications before committing to a purchase.

Specific needs

Before grabbing any random purifier of the shelf, it pays to think of the kind of device you need. Since not all purifiers are created equally, looking at the labels, reading product specs and comparing one from the other. For the most part, air purifiers are designed for allergy relief. These are generally the types that come with HEPA filters to help eliminate allergens indoors.

Aside from allergies, many people turn to purifiers to help remove the presence of smoke, fumes, and even fireplace soot that can be found lingering in the air. Not only does it remove odor, it also removes potential smoke that could further aggravate any existing respiratory issues that are caused by unsavory odors in the environment.

Certain purifiers are specially designed to remove hair, odors, and pet dander. This can be highly beneficial for individuals who suffer from pet related health concerns. More importantly, the presence of these devices is created to be safe for both humans and their animals alike.

More importantly, there are consumers who turn to purifiers in order to contain irritants such as odors, chemicals odors, and allergens that can trigger asthma symptoms. Purifiers to look out for are those that contain chemical and odor filtration, as well as HEPA filtration structures for the removal of allergen particles.

Size matters

Entry level air purifiers are usually of small to medium sizes. To figure out what size will fit your needs, it helps to consider the square footage of the space the purifier is going to go in. Another thing to look into is ACH rate or air change per rate hour. The number of times a purifier can filter the volume of air in a room each hour is the ACH rate. This is vital because a purifier that is able to clean the air in a room at least four times in 60 mins is best for those who suffer allergies and asthma.

As a rule of thumb:

  • Small: Best for rooms up to 299 square feet.
  • Medium: Can be used for rooms that range from 300 to 699 square feet.
  • Large: Rooms that measure between 700 all the way up to 1,900 square feet will benefit from this size.

Features

asthmaEvery brand will market their product differently. Some will produce the standard purifier while others will include unique features that will set them apart from the rest and offer consumers an additional benefit. Some examples are as follows:

Energy Star rating from EPA is a feature to look out for. Having this ensures money and energy conservation for users.

There are also air purifiers that come with wi-fi connectivity for easy control. Apps permit convenient control of the appliance. Some purifiers even work well with home assistants for further ease of access.

Some models come with indicators give real-time updates on the quality of air in a space. This function is perfect for homeowners who want to keep track of this info.

Minor features that still contribute to the overall function of the air purifier such as handles, caster wheels for easy mobility, multiple fan motor speeds, remote controls, and filter change indicators are also useful additions.

Where Should An Air Purifier Go?

Where you are putting the purifier is a key consideration. Will it be used for the bedroom alone or do you plan to move it to a different room when needed? Portable purifiers are designed to primarily clean the environment of one room, selecting several units for other rooms or getting one that is easy to move around may be ideal.

Rooms with minimal floor space will be set from purifiers that can easily be mounted to a wall or will sit nicely in a corner without taking up too much of the floor area. Whole-house purifiers, on the other hand, connect to an existing HVAC system in a home for a more streamlined purification of the air as you cool, heat or ventilate the abode.

Maintenance

The maintenance of a filter will depend greatly on the kind of filtration system it is built with. Some filters will last longer than others, while others will have a shorter lifespan.

Pre-Filters Carbon Filters HEPA Filters
3 months unless filters are washable for long term use. Check with the manufacturer. Filters with activated carbon will last up to 6 months. The longest lifespan of the bunch, HEPA filters can last anywhere between 1 – 6yrs depending on use and on the brand.

Air Purifiers and Asthma

Healthy LungsBesides the standard set of medication, many asthma sufferers also turn towards alternative options and non-traditional methods. Air cleaners or purifiers are devices that work to remove contaminants while improving the quality of air indoors. These appliances are usually marketed as beneficial to those who suffer from allergies and asthmatics. Purifiers are also known to help reduce if not fully eliminate odor and second-hand cigarette smoke.

Countless air purifiers manufactured for commercial use are either small standalone devices or large units that can be mounted onto an air handler unit or on a medical, commercial and industrial HVAC unit.

The question now is whether an air purifier is proven as an effective tool in treating asthma symptoms. Although chronic lung illness or asthma typically manifests in childhood, it can affect people of any age. Studies have shown that the use of air purifiers has been proven effective in relieving symptoms of asthma. It is, however, difficult to prove if the appliance has been effective in preventing it altogether.

Individual air cleaners can eliminate minute particles that are present in the air close to the unit. They are unfortunately not capable of removing small allergens that are a result of local disturbances, such as when a person’s body hits the mattress and then inhales microscopic feces of dust mites in its surroundings.

Furthermore, rooms that are decorated with wall-to-wall carpeting are also large sources of allergens, which stay in the carpeting until it is disturbed. Often times, the brush attachments of a vacuum can cause allergens to float around in a room. In this situation, the presence of an air purifier would provide adequate air cleaning should allergens in a carpet be disturbed.

Asthma symptoms can range from mild to severe. Those who suffer from mild form will notice how symptoms usually disappear on their own. But when the symptoms appear more serious then it is more than likely that a person is suffering from a full-blown asthma attack. Flare-ups or exacerbations are the worst-case scenarios and what many people should aim to avoid. Purifiers not only filter the air, but it also cleans and sanitizes thus offering a better breathing atmosphere for those who occupy the space.

Since the appliance is considered quite the investment, the practical approach is to learn about the top brands and models that are being sold today. These are the 5 best air purifiers and their features to help you make an informed decision before adding it to your cart.


Conclusion

For a lot of asthma sufferers, avoiding organic or environmental allergens that are known to trigger asthma symptoms can play a vital role when it comes to asthma management. Studies have shown that air purifier does help eliminate the presence of allergens in an environment.

Individuals who are looking into air purifiers should find models that can trap micro particles while sanitizing and filtering the air at the same time.
