If your home isn’t affected by many pollutants, we recommend you go for the B4-Fresh Filter. When it comes to filtration technology, we face another draw as both units use the same filter technology. As previously stated, the Classic model is the largest air purifier from the original line of lasko pedestal fans units. Only Alen purifiers have been proven to improve sleep, according to a peer-reviewed study by SleepScore Labs. Incredibly quiet, our BreatheSmart purifiers emit a soothing pink noise, which boosts frequencies in the lower octaves so you can wake up feeling more rested.
But, 50dB (the loudest the Flex is at its highest fan speed) is equivalent to faint background music or a quiet office. In 2018, lasko pedestal fans 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).
Filter replacements cost $99 (Pure), $129 (Fresh), and $139 (Pet) each, but a filter subscription takes 10 percent off the price. A large HEPA filter comes preinstalled in a compartment behind the front panel. Air drawn in through slots on either side passes through the filter and is dispersed through a vent on top.
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 Lasko Box Fan 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.
This is called CADR (Clean Air Delivery Rate) and is measured in CFM (Cubic Feet per Minute) to show us how effective an air purifier is at its job. When it comes to design and filters, both units are almost identical. They have the H13 HEPA main filter that may cost about $100 but needs to be changed only once per year. With other air purifiers, you’re looking at 3-5 filter replacements per year, and a total cost of about $300. On top of that, Alen is the first air purifier brand to introduce a lifetime warranty. By buying the Alen BreatheSmart Classic, you’re playing it safe; the warranty covers all the problems you may have.
In short, the Classic model has great filters that are available at a low long-term cost because you only need one per year, instead of five per year. As of September 22, 2021, Alen’s Forever Guarantee requires enrollment in a air filter subscription. You found the place to register your product, activate your warranty and get the very best from your Alen purifier throughout its lifetime. Reflects how intuitive and easy the controls are to use, carrying ease, ability to remove the filter, and filter life indicator. In an independent SleepScore study, 100 percent of participants said they’d recommend Alen® BreatheSmart 45i and that they planned to continue to use it. With laser sensor automation, and pink noise for a healthier and more relaxing vibe, the 45i is your secret weapon for a more restful night’s sleep.
Owner satisfaction ratings are based on the proportion of members who are extremely likely to recommend their room air purifier brand to their friends and family. We’ve added this extra decibel to the Flex, working a little harder to match the 45i’s cleaning performance. With the exception of their basic B4-Pure filter, they contain various levels of activated carbon pellets. This is used in filters because of its ability to adsorb odors and other VOCs (Volatile Organic compounds).
