ZAFRO A4213-8K Portable Air Conditioners, 8,000 BTU+Drain Hose, White

Working well in a custom installation in a hot Florida garage workshop
This unit is terrific. Just know that any single-hose portable AC exhausts its hot air outside, and for every cubic inch of expelled air, you need an equal amount of inbound fresh air or you’ve made your room into a nifty decompression chamber. That’s great if you get the bends a lot, but it sucks my cheeks in and makes me light headed and sleepy in my little well-insulated light-tight workshop in a hot Florida garage. Since I don’t want to draw in more hot garage air just to feed this AC, I also installed a passive air vent between a shared interior wall of the air conditioned house and my shop. This poppet valve vent can be closed as needed and contains bug screens. It acts like a snorkel on a sub, and provides just enough fresh air and equalization to counter the negative air pressure created by this throttling AC, and with no ill effects on the house HVAC system. And that keeps my personal oxygen engine humming, and cool and happy. This AC is Quiet, smooth running, it’s very effective and the front (vs top) vent arrangement was important for me since I’ve mounted it under a work counter and exhaust it from the rear thru a 6″ dryer vent out the exterior facing wall. Just leave room for fresh air to get in behind it so it will operate efficiently, or fashion an air intake near its rear end. Excellent build, choice and value.

Decent machine, not too loud, but the window kit needs modification to fit.
Easy to assemble, does a good job cooling, and fairly quiet. Under 50dB, on low, from across the room, 63dB right above the machine. It is actually quieter than a 5000 BTU window unit bought locally at the same time.But, the window adapter did not fit a standard 30” wide window! The plastic parts that slide to fit are ~26”, but the outflow port blocks ~10“ of the inner sliding section, so using only the outer piece only covers 26” of the 30” sill, while using both sections requires a 36” window width! The instruction manual only shows it fitting in a vertical position, and such windows may be common in Asian apartments, but are rare in American houses. However, the illustration on the product page shows an idealized cartoon of a horizontal installation. This could be better engineered and explained in the illustrations.So I had to saw off part of the inner slide to fit. The parts for this could be better designed and sturdier, and weatherstripping should be included to get a better fit. I sealed it all with white duct tape to keep it in place, since no hardware or adhesive strips are included to anchor it to the sash and sill. And 1/4” gaps occur above and below the inner sliding section. Not as neat-looking as a proper hardware and weatherstrip install. Be prepared to re-engineer it to fit. YMMV.Otherwise, it is functioning as expected so far. Overall satisfied, but (-1) star for poor design and lack of a more complete installation kit, as typically comes with in-the-window units! I realize it is meant to be “portable,” and not permanently attached to the window, so not (-2) stars, but still needs a rethought design to better fit standard windows.

This helped me be able to sleep upstairs
My central is not efficient for upstairs. I bought this for my bedroom. It was a lifesaver. Gets super cool. You do have to empty the tank, but who cares. It makes noise, but not annoying.
