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.
Alen®’s BreatheSmart technology lets you monitor room conditions from your smartphone. We make the invisible visible, so you can verify that your units are removing harmful pollutants from your home – in one or multiple rooms. Designed to service rooms as large as 1,300 square feet, the 75i offers a beefy CADR of 347 cfm at the highest of five available speeds. (No breakdown for different pollutants is provided.) An option lets you turn on an ionization feature, in addition to the unit’s standard HEPA filtration system. If one of these fits in with your décor, it can certainly take some of the sting out of the dominating size of the unit. Just keep in mind that you’ll pay a $39 premium over the $749 asking price for any color aside from white.
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.
By putting it through its paces in various real-world tests, it proceeded to tick all the boxes. Working well at eliminating odors from cooking and nearby breweries and noticeably reducing allergies to pollen and dust while being extremely simple to operate and maneuver around the home. Alen states the sound levels of the purifier are 39 dB at speed 1, 42 dB at speed 2, 49 dB at Speed 3, and reaching 55 dB on turbo.
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.
It runs on average quieter than air purifiers with similar clean performance and is backed with a lifetime warranty as long as you purchase a filter subscription. 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. The capacitive control panel allows you to cycle through the settings easily.
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.
