Yes this model is the best T-Hood under rubine. If value for money IA90SM would b a better buy for it is a slanted hood and may be you dont like the design.

IA90D price is too expensive and close to Fotile, so most of my customers might as well get Fotile.

High suction does not equal to better performance but high suction definitely means higher noise level. We are having clearance sales today, u can drop by if you need more info and also better offer.

Thanks for your recommendation, zheilwane!

At last, I have chosen RCH-IA90D-GX + RGH-TONIA2B-90BL.

I got a friend using mesh filters. According to him, the performance is not good after a while. After I did some homework, I found that mesh filters require frequent cleaning compared to baffle filter.

Here is a simple comparison
