YJINGRUI Laminar Flow Hood, H-14 HEPA Filter with Safety Locks, Class 100/ ISO Class 5 Cleanliness, Fan Filter Unit 22.6x22.6in Flow Hood Mycology/Clean Room/Laboratory 110V

Pretty laminar, seller was very responsive with my questions. Good price as well, highly recommend!

At first I was going to leave a one star review because both the original and replacement units arrived with damaged filters, which is the most crucial part of this FFU, but the seller ultimately made it right.There is a good chance you may, or may not receive a factory second, as I did, but a friend of mine received one with a perfect filter, and one minor imperfection on the filter attachment hooks, which had no impact on operation.The replacement filters are expensive, but should last at lest a year. I would suggest buying a 15" x 15" pre-filter to add to the back of the unit.Overall, it's a budget friendly FFU that works well for the amateur mycology hobbyist, and I am not unhappy with it's performance, or at least won't be after I receive an undamaged filter.UPDATE: The seller went above and beyond to address my issues, and the replacement filter arrived in perfect condition. I am very happy with my purchase and highly recommend it.

This product (sold by many on Amazon) is not a Laminar Flow HoodThe fan has three settings Low, Medium, High. On the low setting, the amount of air flow will blow out a lighter an inch from the filter. The fan is overpowered for this unit only provides turbulent air flow.I will be returning this item and strongly advise potential buyers to find a legit Laminar Flow hood.

Using my filter gives me a sense of Secured, like there are less contaminants in my space. I have had less contaminants. But, at the same time the strong chemical smell makes me wonder..

BUY THIS!!! Early reviews mention filter damage from the delivery. Seems the seller was on top of filter replacements but I think they have fixed the issue. Mine came in perfect condition double boxed plus Styrofoam supports. As far as value for your money you can't beat this. The unit is built very well and I'm seriously stoked with it.

Shipped very fast and somehow came across the country faster than something shipped from the next state away. Great price, seems like a decent lower priced option. Thin sheet metal, workmanship with screws etc. arrived in a foam box inside a cardboard box. The issue is any outside pressure transmits directly to the fragile filter and sheet metal box. A single hole in the cardboard from a drop, dented the filter and damaged the pleats on the face of it. Confirmed with a lighter test. Two of four corner brackets to hold the filter in place had missing rivets and were bent. Two of the 6 toggle latches were damaged and weren't usable. AMAZON told me the only recourse was for a full refund and return. The latches/brackets are simple , the filter needed replace though. After I returned it the seller messaged about sending another filter. Appreciated it but Amazon already has the unit for 9 days now and am awaiting the refund.

Most of the negative reviews on this product seem to be about it being damaged in transit. I think the company has addressed that issue, since mine showed up almost bomb proof. The packaging was very sturdy with almost no chance of damage unless the guys in shipping were using it like the monkeys in that commercial for samsonite luggage. As far as the operation, it wasn't loud, and had good air flow. It is heavy, so having a permanent place is a good idea and the clasps could be better designed so it sits flat, but those are just nit picking. All and all, this seems like it will be a good addition to my mushroom farm.

This is totally worth the money absolutely great for what I needed it for. No damage no issues "5 star"
