Every attic should be well insulated and well ventilated. We have covered the recommended attic R insulation values here. Here we are going to look at the ventilation part, specifically, what size attic fan you need in terms of CFMs. Attic fans come in all sizes; from the smallest 80 CFM attic fan to over … Read more
With a bathroom exhaust fan, you have to install adequately sized ducting. The problem is that there is no universal standard bathroom exhaust fan duct size. We are going to look at all duct sizes for bathroom fans (you can check the all-encompassing 4-9 inches ducts fitting 50-250 CFM exhaust fans further on). Namely, bathroom … Read more
If a ceiling fan capacitor goes bad, you will know it. In more than 80% of cases we see the ceiling fan spinning slow (fan running slow), the culprit is a faulty capacitor. We are going to look into how to tell if a ceiling fan capacitor is bad; you will be looking out for … Read more
No one likes a loud floor fan (especially in the bedroom). Floor fans are quite useful to provide ventilation and cooling, yes; but they tend to be quite noisy. The easiest way to deal with this is just to pick the quietest floor fan possible. Now, how do you figure out which floor fans are … Read more
High velocity floor fans are true airflow powerhouses. Due to their high airflow generation (even more than 5,000 CFM), they can be used to ventilate big spaces, including garages, warehouses, basements, workshops, gyms, and so on. Obviously, regardless of the place you are going to use it for, everybody wants to get the best high … Read more
Wall-mounted fans are the easy space savers. You can install them on any wall, don’t need to be hard-wired, they don’t take up your floor space, and can provide both cooling and adequate ventilation to any space. Picking out the best wall-mounted fan, however, can be quite a bother. There are so many of these … Read more

Does a bathroom exhaust fan need to be vented outside? Not necessarily. In short, there are two major categories of bathroom exhaust fan venting … Read more
CFM per watt (CFM/watt) is the basic unit for measuring fan airflow efficiency. It is defined as the amount of airflow (measuring in CFM or Cubic Feet per Minute) a fan can generate per 1 watt of electric power input. Here is the most basic sense of how to think about fan airflow energy efficiency: … Read more
