GermGuardian FLT4850PT True HEPA with Pet Pure Treatment GENUINE Replacement Filter B for AC4800/4900 Series Air Purifiers by Guardian Technologies

After a rat outsmarted pest control's traps and poison, we tried this device. Turned it on at night—problem solved! It kept the rat out of our kitchen, and I plan to use it for insects in summer. A cheap camera confirmed it works. The only downside is a faint noise on vermin mode, but it's worth it for a pest-free home.

As for mice, we’ve never had an issue, but since our new place showed signs of past activity, we’re playing it safe. Between the wire wool, mint sachets, and these plug-ins, any mice thinking about moving in should hopefully get the hint!

I used to occasionally spot roaches in my apartment, so I decided to try these as a preventive measure. So far, they seem to be working，I haven’t seen any roaches, even during the time of year when they’re usually more active. I placed one in each room, which gives me some extra reassurance.

I’ve been really impressed with how effective this pest repellent is. The difference is noticeable, far fewer bugs around! It runs quietly, requires no maintenance, and doesn’t affect my pets at all. Love that it keeps my home pest-free without any toxic sprays or traps。
