My eco hero: #2
David Hilton nominates a product which is a breath of fresh air Mechanical ventilation involves getting fresh air into your home and taking stale air and pollutants out. But what happens when the air you bring in is not exactly fresh? You may live near a busy road, there may be lots of pollen in the air, or possibly dust or pollution from local industry. Step in the Blauberg Clean Box: the filter box cleans the air entering your mechanical ventilation system, whether it’s MVHR or simply a forced air ventilation fan. It has three sets of filters: a coarse dust filter, a PM2.5 particulate filter, which protects against particles and aerosols 2.5 micrometres wide, and a NOx filter, which filters fumes from petrol and diesel engines. The Blauberg CleanBox ranges in price from around £250 to £400 depending on duct diameter. In my view, it‘s a very good addition to a ventilation system in homes where clean air is a priority.
