Well…. Maybe. It can be all good, but it’s up to you to make sure your filter is clean if you have an over the range microwave in your kitchen instead of a hood system. Not only is it vital for the safety and proper operation of the unit, it will go a long way in maximizing the limited functionality of odor and smoke removal if you’re cooking without a hood system.
Here’s why: Typically, OTR’s have lower CFM’s (cubic feet per minute) and recirculate steam and smoke back into the kitchen after passing through a charcoal filter. Though OTR’s don’t completely remove odors and smoke from your kitchen (and they won’t remove any heat), they will remove some of the grease and odor particles IF you are changing the filter regularly, which means at least once a year. Some models don’t even require a replacement filter; you merely have to pop it out and clean it yourself, which sounds like a really exciting way to get your weekend started, am I right?
Be sure to check with your manufacturer for the specific filter and its model number, or contact one of our knowledgeable sales representatives to help you out, like me!
