Motoasis 【Upgrade】 Model 8814 Fan Motor: Breathe New Life into Your Bathroom Fan

Tired of that noisy, struggling bathroom fan? The Motoasis 【Upgrade】 Model 8814 8663 8673 fan motor promises to be a direct replacement for several Nutone models, including the popular 8814R and 8673RP. This 110 CFM fan motor aims to provide quiet and efficient ventilation, improving air quality and reducing moisture in your bathroom. It claims to be compatible with a wide range of Nutone units using the standard 9"x9" housing.

This fan motor is designed for homeowners seeking a DIY-friendly solution to revive their existing bathroom ventilation system. Instead of replacing the entire unit, which can be a costly and time-consuming project, you can simply swap out the motor. If your current Nutone fan motor is making excessive noise, not pulling air effectively, or has simply stopped working, the Motoasis 【Upgrade】 Model 8814 might be the perfect fix.

Key Features of the Motoasis Fan Motor

Here are some of the key features that make the Motoasis 【Upgrade】 Model 8814 fan motor stand out:

  • 110 CFM Airflow: Provides strong ventilation, moving 110 cubic feet of air per minute to quickly remove moisture and odors.
  • Low Noise Operation: Operates at a relatively quiet 3.5 sones, reducing unwanted noise in your bathroom.

  • Improved Airflow: The 110 CFM airflow effectively removes moisture and odors, leading to a fresher and more comfortable bathroom environment.
  • Cost-Effective Solution: Replacing just the motor is significantly cheaper than replacing the entire ventilation unit, saving you money on parts and labor.
  • Wide Compatibility: The motor works with many existing nutone models.

Cons: What Could Be Better

  • Durability Concerns: While the motor performs well initially, some users have expressed concerns about its long-term durability compared to original Nutone motors. Only time will tell if it lasts as long.

Good value for the money. They are a bit thinner than the original Bissell bags but I haven't had one rip yet. Definitely saves me a lot of cash since we vacuum every day with two dogs.

LOVE this halter!! My mare responds so much better to this than a standard bit. It’s gentle but gives me the control I need for trail riding. Total game changer for us.

They work fine and the 4-pack is convenient but I'm not totally convinced they're worth the premium price over some of the generic MERV 8 brands. The build is solid but idk if my air feels "better" than before, it's just a filter lol.

Great little end table/record stand. I use it for my player and keep my favorites in the bottom rack. It was pretty easy to assemble alone, took maybe 30 mins. Solid purchase.

It's a decent product for the money, but it lacks the complexity of modern aftershaves. It’s very "one note" leather and wood, which is fine if that's what you're into, but I probably won't buy it again once this bottle is finished.
