- 300 CFM vent fan with 2 speeds
- 10 power levels
- Push-to-open PureAir filter door with indicator light
Who it's for
Anyone replacing an aging over-the-range microwave who wants a straightforward, no-frills unit with a name-brand vent fan. Buyers used to physical push buttons should expect an adjustment period to the touch controls.
What buyers say
From Amazon customer reviews.
Reviewers consistently call it quiet in operation and straightforward to install using the included templates, with one full install taking about two hours start to finish. The touch-screen controls draw mixed reaction: functional but requiring more deliberate pressure and a short adjustment period compared to physical buttons. A couple of owners note the door is noisy when closing and there's no option to turn off the completion beep.
Strengths and trade-offs
Drawn from this product's published specifications.
- Quiet operation compared to older over-the-range microwaves
- 300 CFM vent fan with two speeds
- Installs with included templates in about two hours
- PureAir filter with indicator light for change reminders
- Touch controls need a short adjustment period versus push buttons
- Door can be noisy when closing
- No way to disable the completion beep
Performance notes
The 300 CFM fan across two speeds handles range venting, while the 1500W magnetron and 10 power levels cover standard reheating and cooking. Reviewers consistently describe the unit as quiet compared to previous microwaves, and installation using the included mounting templates typically takes about two hours including removal of the old unit, a 3/8 inch spade bit and a 2 inch hole saw.
