Best Air Purifier for Allergies

Coughing, sneezing, a runny or clogged nose and watery, itchy and red-rimmed eyes are sometimes not the symptoms of cold. Instead, a number of times these unpleasant symptoms are the unwanted gifts of some kind of allergen that is swirling around in the air. To eliminate these allergens and the threat of getting sick, bring home the best air purifier for allergies.

What is ‘Allergy’?

‘Allergy’ might be one of the most common words spoken in your household. Whenever you hear the word, conditions like runny or clogged nose, seemingly unstoppable coughing or sneezing, watery eyes and sometimes even difficulty in breathing comes to your mind. But the mentioned troubling conditions doesn’t define the term ‘allergy’ but merely list its symptoms.

In the air, various substances are circulating. Sometimes these substances, called allergens, compel the body’s immune system to respond in an inappropriate way if they pose a threat to the individuals.

This body’s immune system’s response is defined as an allergy. An allergen doesn’t always trigger the same response in everybody. For most of the people, these substances are harmless, while for some they cause an antibody response.

Different effects of allergens in allergic and non-allergic people

It is stated in the above section that all allergens do not activate the body’s immune system in all people. These allergens are generally viewed as harmless by most of the population. But for some of us, they prove to be nightmares.

It is a common scientific belief that tendency to get allergic is an inherited trait. If a parent is allergic, there is a 25% chance that their child will be too. Allergens also attack people with weak or lower body defenses for example during viral infections or pregnancy.

So, allergens stimulate a response from people who have a likelihood of developing allergies because of one or more allergens while others people remain unaffected. They either swallow or cough out these allergens.

Allergens and associated allergies

Before going into extensive detail regarding the solution of allergies and how the best air purifier for allergies successfully tackles the issue, let’s first put some light on the subject of allergens and the allergies they cause.

1. Pollen:

Pollen grains are microscopic particles released from plants. Using air as their transportation medium, the pollen grains move to other parts of the plant with the intention of fertilizing them. But not all pollen grains reach their desired target. Sometimes people inhale these minute substances or swallow them. This might cause pollen allergy. Out of all types of allergies, pollen allergy is very common.

2. Mold Spores:

Mold spores are tiny airborne particles that thrive in moist and shady places like damp basements, closets, and bathrooms etc. On few occasions, these mold spores escape the protective mechanisms designed to keep the harmful substances from entering your nose and upper respiratory tract. On reaching lungs, they cause various allergic reactions.

3. Dust mites:

Dust mites or bed mites as some people call them are tiny bugs who despite their small size can stir up a lot of trouble. These microscopic creatures are found on mattresses, bedding, carpets, curtains and upholstered furniture and cause allergic reactions that are similar to symptoms of pollen allergy. Dust mites are a common cause of asthma too.

4. Pet allergens:

If you are fond of pets, you might not be unfamiliar with this kind of allergy. Urine, dander, and saliva contain proteins that after drying freely float in the air and serve as allergens. Pet allergy is slowly developed and takes around six months or sometimes even more to subside.

Apart from pollen, mold spores, dust mites and pet allergens, there are other pollutants circulating in the air that forces our immune system to respond for example viruses, bacteria, and smoke etc. Specially, to get rid of smoke, some special features such as in air filter for smoke will be explained

What methods other than air purifiers can be used to remove allergens?

Because on rare occasions they can be life-threatening. Purchasing the best air purifier for allergies is the quickest and easiest way to deal with the issue. But there are other ways to eliminate the allergens circulating in the air.
