Another consideration you need to make when buying an air purifier is the cost of replacing the filters. The filters in air purifiers need replacing periodically (the manufacturer will tell you how long they last on average), and it’s Lasko Box Fan not recommended that you wash them. When it comes to noise levels emitted, the winner is the 45i, as it generates less noise. Although the 45i is only one decibel quieter than the Flex when running at its highest fan speed level.
That’s why we wanted to get our hands on a few of their products to test and review. This Austin-based company has been engineering and innovating since 1999, so they have a wealth of knowledge behind them. Their mission is to ” improve the quality of people’s lives” with their products; their vision is to “inspire a healthier life and provide peace of mind” for their customers. Sadly, the noise levels are also a bit of a con for the Classic model, paradoxically so I may add.
If you see the blue light, you can lower the speed to Speed 2 or even Speed 1. The cost of the Classic model filter ranges from $79 for the Pure filter to $119 for the OdorCell filter. The beauty of this is that you only have to replace filters once per year; with other alen breathesmart air purifiers, having to replace filters 3-5x per year is the standard. Alen’s signature color ring signals what it’s sensors are detecting in your Utopiair TM. Watch as your Alen kicks into gear when conditions change to give you purity that never stops working.
Both units have four fan speeds, including T for Turbo, so you would expect that they would emit the same amount of noise. But the Flex is ever so slightly louder than the 45i on paper, though we doubt you’d notice the difference with them running side by side. Every unit we review goes through the same performance tests where we fill our office (705 cubic ft) with simulated pollutants.
If you don’t, the filter won’t do its job, and the plastic may start to burn over time. They may be identical from the front, but when you look from above, you’ll see the differences on the control panel. Alen has always been known for their top-of-the-line filtration systems. That’s actually the most important part of any air purifier; filters are the very thing that capture airborne pollutants and eliminate them from the air circulation.
But, 50dB (the loudest the Flex is at its highest fan speed) is equivalent to faint background music or a quiet office. In 2018, Alen BreatheSmart Classic was one of the best large room air purifiers. High CADR rating, aesthetic design, the addition of real-time indoor air quality sensors, and the advanced H13 medical-grade filter were great qualities back then. In this review of the Alen BreatheSmart Classic, we’ll look at the specifications that make the Classic one of the best air purifiers for large rooms. In short, it removes indoor air pollutants like dust, pollen, and smoke down to 0.1-microns exceptionally well (99.99% efficiency).
