#1. AlenBreatheSmart Classic Air Purifier for Large Rooms
This classically designed air purifier from Alen is one of the top models on the market. It can cover a significant amount of space, able to purify 1,100 total surrounding square feet. Because of this, it’s a fairly expensive investment. If you don’t need to cover a huge area, you can find air purifiers that do the same job with a smaller amount of coverage and a fraction of the price.
One place you might use this air purifier is in a large open basement or attic, especially if you’re dealing with mold and mildew. Until you can get rid of the cause at its source, you want to make sure there aren’t any spores in the air. In addition, cleaning and mold removal professionals might bring this air purifier to job sites while they work.
Though the purifier is made for residential homes, it may also be effective in industrial and commercial sites. There are a variety of different purifiers with different filtration systems. You’ll want the one optimized for mold and bacteria. With that said, there are also options for purifiers that specialize in pet dander and odor or allergies and dust.
Many purifiers on the market are only available in one or two colors. But this model is available in eight pleasant and neutral tones. There’s a pure white option, a few sleekly metallic choices, or finishing options that resemble a wooden grain. You can find the one that most suits your decor and personal aesthetic.
TheBreatheSmart design was originally developed by NASA engineers to help with airflow in space. It’s so efficient that it can clean a total 1,100 square feet of space in just thirty minutes. An entire floor of your home can be purified twice in an hour. In addition, the design incorporates patented WhisperMax technology to reduce noise levels.
Though this model is optimized for mold and mildew, it can tackle a lot more than that. The filtration system also gets rid of common allergens, light odors, dust, and chemicals in the air. The filter has been HEPA certified, which means it can remove a minimum of 99.97 percent of particles. In addition, there’s an antimicrobial coating that keeps fungi and bacteria from growing on the filter.
Before the particles move through the HEPA system, they go through an activated carbon filter. The 1.5 pounds of activated carbon trap and neutralize particles like dust, mold, household chemicals, and cigarette smoke. Since the carbon filter traps large particles, the HEPA filter lasts longer.
The model is equipped with smart technology that consistently measures the air quality in the room. It can detect particles down to sizes of 0.3 microns. There’s an air quality light that will let you know about the air quality of your room at any given moment. If you set the purifier to automatic mode, it will adjust the fan speed to provide energy-efficient filtering for your changing air quality conditions.
The purifier also comes with a lifetime manufacturer’s guarantee. Most competing models only have warranties that last a few years at the most.
#2. Fellowes AeraMax Large Room Air Purifier
This is a much more affordably priced option, though it may still be a little pricey if you’re working within a constrained budget. The purifier is designed for large rooms rather than open spaces, and it’s able to purify anywhere from 300 to 600 square feet of space at a time. You can purchase the model in either black or white.
As with any high-quality purifier, the model comes with a true HEPA filtration system that has been tested and proven to remove at least 99.97 percent of particles. There’s also odor eliminating technology that uses a carbon filter to capture germs, mold, dust and smoke. It’s designed for individuals with asthma and allergies.
Like the previous model, the HEPA filter has received an antimicrobial treatment that prevents fungus and mold from growing on the filtration system. You don’t have to worry about hazardous conditions and bacteria.
Smart technology has been incorporated into this model as well. It has a sensor that continually monitors your air quality. Though it doesn’t have the same light-up air quality alert system as the previous model, it does provide automatic fan adjustment to keep the air purified as efficiently as possible.
The Asthma and Allergy Foundation of America has given this product a certification of asthma and allergy friendliness. In addition to normal filtration modes, there’s a high performance mode that can be used for flu, cold, and allergy seasons. If you’re dealing with rooms that have significant mildew or mold, this mode is a lifesaver.
There are four components to the filtration process. First is the carbon filter, followed by the HEPA filter, and then the ongoing safety of the antimicrobial coating. The last piece is PlasmaTRUE integrated technology, which creates ionized fields that remove airborne pollutants.
The HEPA filter has an average lifespan of 12 months, though it may need replacing sooner if it works in highly polluted areas. The same is true of the carbon filter, which should be replaced every three months on average.
#3. Alen T500 HEPA Air Purifier
This is another air purifier design from Alen. Alen is at the forefront of air purifier technology. Since it’s able to purify up to 500 square feet, it will suit most large rooms.
In addition, the design is much more compact and portable than many of the others on the market. The vertical filtration system means that you can set the purifier on a table, the floor, a counter, or a desk without taking up too much space. The model is available in both black and white.
The HEPA filtration system filters out the majority of particles in the air including common allergens, dander, pet hair, dust, mold, mildew, pet odors, and odors from diapers. Because the coverage is powerful without breaking the bank, this air purifier is a great choice for anyone who needs it in their baby nursery, office, dorm, bedroom, or living room.
The compact tower design has received an Energy Star certification for low power consumption. As such, you don’t have to worry about it running up your power bill even if you leave it on constantly. With three speeds available, you can choose the level of efficiency you want. At the highest speed, the purifier consumes 53 watts of power.
Like the other Alen purifier on the list, this model comes with a lifetime manufacturer’s warranty. Should the purifier break, you can either get a replacement or repair free of charge.
This air purifier doesn’t have an automatically adjusting setting or an air quality sensor. However, thanks to the Energy Star certification, you don’t need to worry much about it eating into your energy consumption.
The BreatheSmart Classic air purifier is the most powerful one on the list, and it’s among the most powerful on the market. This purifier can handle up to 1,100 square feet at a time. As such, it’s good for open floor plans and large spaces. If you want to purify your entire apartment or a whole floor of your home, this is the machine to get. It is the most expensive option, though.
The AeraMax air purifier from Fellowes is another high-quality purifier that can handle mildew and mold. It has an activated charcoal filter that absorbs mold and odor-causing spores, followed by an anti-microbial HEPA filter. You can choose whether to get the model in white or black. This is a more affordable model that covers between 300 and 600 square feet.
The T500 air purifier is another high-quality option from Alen. It covers a maximum of 500 feet, so it’s a good option if you want the technology of the BreatheSmart but don’t need the excess coverage. In addition to helping with mold and mildew, the T500 gets rid of other odors and common allergens. The design is both sleek and compact, easy to fit onto a desk or table or the floor. You can move it simply from room to room throughout the day.
