Your bedroom is the best place to keep an air filter because that’s where you spend most of your time. Both these air purifiers have been engineered with almost similar features and performance levels. Alen 45i is ideal for smaller rooms, while 75i works best in larger rooms. In my opinion, there are hardly any differences and both win in their own ways.
1) Designed to purify smoke, pollen, and dust from the air in mid-sized to large rooms, as well as many smaller homes and apartments under 1,100 square feet of total floor space. It is the most powerful filter ever existed and works extremely well for consumer use. It filters the smallest particles down to 0.3 microns including all sorts of dust, germs, mold, pollens.
As an added safeguard, Alen’s proprietary antimicrobial treatment kills mold and bacteria. Elevate your indoor wellness with Alen’s bestselling True HEPA air purifier—featuring advanced particle sensor technology. The 45i quietly purifies up to 800 SqFt of air every 30 minutes, removing 99.99% of dust, allergens, aerosolized viruses, and other contaminants down to 0.1 microns. As a SleepScore Validated product, the 45i has been shown in studies by SleepScore Labs to helped people achieve better sleep and feel they have fewer allergy symptoms. While the BreatheSmart 75i isn’t too expensive to run for a year in terms of electricity, you will need to replace its combined HEPA and carbon filter once a year.
That’s more than double the replacement cost of the top-ranked Brita. In conjunction with this, the more high-tech air purifiers can employ an extra Lasko Box Fan line of defense. There are also models that can ionize incoming particles, which are then sucked in by metal plates or other treated substances.
Are you looking for protection from allergies or just need to freshen up the air? A quick look at the specs for the purifier should tell you what particles it can effectively remove from the air. Again, a HEPA filter is going to do the trick for most common irritants and odors, including pet hair and dust.
The lights-out mode turns lights off and provides soothing pink noise for better sleep. Here are the products you need to detect potentially harmful contaminants in your home and ones that help reduce those levels, too. Indoor air pollution—from mold, radon, cooking gasses, and more—can pose a serious health threat. Here’s how to combat harmful contaminants in your home, and some useful products to help.
Annual cost is a combination of yearly filter and energy costs. Equipped with 2+ lbs of activated carbon to absorb smoke and chemicals. Pleated filters have larger surface areas to trap more dirt. The greatest thing about this product is that it is very easy and simple to use.
