When he’s not putting a purifier through its paces, Paul likes to endlessly dig through dusty record shops (making his dust-free apartment even more important). Auto Mode intelligently adjusts its cleaning power to achieve the best air quality while maximizing air filter life while saving energy and money. Auto mode allows our intelligent sensor technology to adjust to your changing environment. LED indicator always lets you know the status of the air quality around you.
Dust, pollen, smoke removal is how well a model cleared air of fine clay dust and cigarette smoke when operating at a low speed that was typically one setting above the lowest speed. Many models have multiple speeds and the lowest is not as effective at cleaning the air. A model that scores well for dust removal should perform comparably for pollen. Although its price lasko pedestal fans comes in at the higher end of the mid-range market, you’ll struggle to find another purifier for under $450 that boasts 5 air changes per hour in an 800 sq. Ft room with a CADR rating of 245, along with the real-world performance to back it up. The smart features include App support and an accurate auto mode that switches on when it detects pollutants in the air.
This is quite a long lifespan for a HEPA filter, with many other manufacturers suggesting replacing the filter after 6 months or a year if used infrequently. However, as the replacement filters cost up to $119, I hope it proves true. In reality, the power consumed will be much lower as the purifier operates on the lowest setting 99% of the time. Each of Alen’s True HEPA filters can capture 99.99% of airborne contaminants lasko pedestal fans down to 0.1 microns, which are certainly impressive figures and was something we saw for real in our performance tests. However, these results reflect controlled lab testing, so I was keen to see how these figures translate in the real world. Once everything is unwrapped, open the front hatch via the air inlets on the side of the machine and slot in the HEPA filter, with the pre-filter facing towards you.
When we switched on the Alen 45i at full power with the ionizer, it removed all particles in 33 minutes. When purchasing the Alen Breathsmart 45i, you are given a range of filters. Each filter offers a slightly different level of protection, mainly in relation to odors and volatile organic compounds (VOCs). With customizable designer panel colors, the BreatheSmart can be personalized to fit any room and compliment your decor for today or whenever your styles change.
There are five colors, from purple, which is poor through to red, orange, green, and blue, which signals excellent air quality. For our latest review, we’ve turned to the Austin-based air purifier manufacturer Alen to put the BreatheSmart 45i through its paces. Alen is widely regarded as one of the top innovators on the market, creating high-performing purifiers and long-lasting filters. BreatheSmart is designed to effectively purify your air in large and open living room up to 1,100 sq ft leaving you fresh, pure air in under 2 hours.
I went for the ‘Fresh’ model, which contains a medical-grade H13 True HEPA filter plus an activated carbon filter for added protection against VOCs and smoke. ? The replacement filters are expensive.? The cheapest filter option doesn’t have an activated carbon filter.? Being provided with 3 different power cables for various regions is unnecessary and wasteful. Speed can be adjusted manually or using an automatic mode, and a countdown timer lets you shut the unit off after two, 4, or 12 hours.
Alen’s medical-grade filtration is highly effective thanks to powerful yet quiet airflow, ensuring pure air for your entire room. As an added safeguard, Alen’s proprietary antimicrobial treatment kills mold and bacteria. As a light sleeper, I thought utilizing the purifier in the bedroom would be a no-go area. However, I was pleasantly surprised to find on the lowest setting, it is barely noticeable. I also had no issues on the second lowest setting, which may have even helped send me off to sleep with its gentle ASMR pink noise hum. Rather than a mere design feature, this light’s color indicates the air quality in the room.
Noise is based in instrument measurements with the model running at a low speed. The lowest speed may provide even quieter operation but will not be as effective at cleaning the air. The amount of electricity the device uses and how often you have to replace filters.
The next step was sealing up our 150-square-foot testing room and filling it with smoke by burning paper and other testing materials. We monitored the air with a Dylos air quality monitor; once the room reached our desired level of airborne particulate pollution, we kicked on the BreatheSmart 75i for an hour. After 30 minutes, there were only 16.62% of the original particulates left floating in the air, .003% after 45 minutes, and 0 detectable particulates after an hour. While the odor from the burnt paper wasn’t entirely eliminated, it was severely reduced.
