Alen BreatheSmart Classic Air Purifier Review

Alen BreatheSmart Classic Air Purifier marketed itself with certain features which interest me. Being someone with allergies and pet dander, I was also looking for a cleaner. Since I was already aware of the cleaner via consumer reports and on certain commercial websites, the product has a rating of 4.6 out of 5; so in a heartbeat, I got BreatheSmart Classic home, and I can proudly say that ‘I was right.’ The purifier changed the air around my surrounding. Now I breathe healthy air, and my home looks and feels clean. It’s been a while since I stopped using medications for my allergies, and I don’t regret making this purchase.

I also found out some fascinating factors about the cleaner. The unit is ozone-free, which means the unit manufactures negative ions that collect particles and makes it simpler for confining molecules inside the HEPA filter. There is 0 PPM when the unit is detached and below 0.050 PPM when engaged with an optional ionizer. Also, the unit requires 1.6-105 watts of power consumption which is relatively standard for a practical yet powerful purifier and power supply of 120 AV, 60HZ. If you use the cleaner for 8 hours every day, you may spend only $43 every year.

What amazed me is that the BreatheSmart air purifier provides a lifetime warranty and assures that the products are free from any defects. If found any, the company will issue for replacement. Moving on, I also discovered that the cleaner consists of adaptable HEPA type filter which comes in various options to address particular needs such as-

  • HEPA-FreshPlus incorporates an activated carbon filter, which helps to remove household odors and proves helpful to people with sensitivity towards VOCs
  • HEPA-Pure, which is the standard HEPA filter traps 99% of pollutants and gets rid of dust and ordinary allergens
  • HEPA-Silver can be a little more pricey than the rest, but if you want to be free from mold spores or bacteria, this filter will help with its anti-microbial silver-ion threads.
  • HEPA-OdorCell is known as the ultimate HEPA filter due to its distinctive Alen’s Molecular Conversion Powder, which gets rid of cigarette odors and heavy airborne odors

These filters are no ordinary ones as they fall under H13 HEPA filters and remove every small particle. The filters can last for 12-15 months despite using them daily. These filters range from $79 to $119, and you can replace them once a year. It’s been nearly a year since I made my purchase, and it looks like my filter is still doing great.
