At the end of the day, there is bound to be one pollen air purifier or HEPA air purifier mold that can assist in alleviating your allergies troubles.

Mold Poisoning Symptoms and Health Effects

Mold poisoning can be a serious health issue when not handle with proper care. From the mild irritant symptoms like flu, watery eyes that is hard to call if is mold-related, to your allergy-triggering symptoms like asthma, eczema, migraine, chronic cough, nausea, and diarrhea. The toxic released from mold can also lead to health risks like mental disorder, autoimmune disease, respiratory and liver failure, reduce eye sights, neurological damage and even reproductive capability. It’s always better to be safe than sorry with Mold.

How do we measure?

Pollen CADR Regardless if the allergens are mold, pollen or mildew, the higher pollen CADR scores, the better it is. Measured in CFM (cubic feet per minute) on the amount of clean air that flows out of the air purifier, we pick Pollen CADR for our air quality testing because it is reliable and industry standard measurement by AHAM (Association of Home Appliance Manufacturers). Not all manufacturers participate in the high-speed test so the next HEPA filter is also an equivalent or perhaps for some, even higher measuring factor.
HEPA filter Pollen, mold spore and mildew are all microscopic allergens that in single cell airborne form is hard to be seen through our naked eyes. Only a true HEPA filter would have the capacity to get rid of these microbe irritants and that is precisely what we are looking for. To be part of our prestigious list, the air purifier must be equipped with a genuine HEPA filter capable of removing microscopic allergens from the air. Bonus add points will be given to the air purifier filtration that plays well with other filters in order to maximize the filter’s efficiency and lifespan.
Room size/ Coverage Never underestimate the speed of mold and pollen infestation. Mold can spread around the house within 24 – 48 hours and slowly colonizes your home space one inch per day. Pollen is no slouch either that spread into our breathing space rapidly as it’s mostly airborne. An air purifier with substantial purifying coverage would have no problem covering an entire room size from allergens intrusion. Obviously the wider purifying coverage the bigger room size it can support, that cannot be the sole factor in determining the best mold air purifier. We also judge the air purifier based on its size, intended category, airflow distribution speed and of course the cost of ownership.

Who is this for?

First and foremost people that has been officially diagnosed with pollen allergies by a doctor or allergist. Secondly, a person that is suspected to be allergic to pollen/ mold with seasonal symptoms as above mainly on a runny nose. Staying close to nature or has lots of tree/ plant with open windows all the time. An asthmatic person especially on children or elderly people that is at higher risk in triggering an asthma attack. Lastly, anyone that needs clean air throughout the day free from pesky pollen, spores, and mildew.

Blueair Classic 605 does have its fair share of downside and is "gigantic" literally. The bulky and heavy size does not fit well in constraint spaces. Blueair 605 is also very expensive both in cost and filter replacement.

Alen BreatheSmart Classic is another popular air purifier for mold with high pollen CADR output and still cheaper than the above-listed models. While the basic HEPA-Pure filter is good enough to cover for standard allergens, you will have to upgrade to at least HEPA-Silver to take full advantage of the air purifier effectiveness against microorganisms like mold.

Equipment wise, Alen BreatheSmart Classic is also well-covered with timer, remote control, air quality sensor plus Auto mode where you will appreciate the convenience of autonomous purifying.

As a console pollen/ mold air purifier, nothing much negative you could associate with Alen BreatheSmart as it is well-balanced in performance, spec, and price. The closest alternate model that would give it a fight would probably be the cheaper but slightly inferior Winix HR1000.

From Winix HR1000/ HR950 to Winix U450, most Winix air purifiers would fit well in our best air purifier for mold/ pollen list.
