Overview

AVG TVA20HF-LF HI-FLOW commercial tempering valve has BSP 20mm 3/4" compression fittings at all three ends and features copper olives. Australian Watermark Approved. The tempering valve's higher flow rate valve allows for increased flow at lower inlet pressures. 

The TVA20HF-LF tempering valve can automatically mix the cold and hot water inputs and outputs a steady 50 deg hot water after mixing. The commercial tempering valve is required in Australia by law in the plumbing rules as it is a safety device. Without mixing, the hot water straight from the hot water services can exceed 70 deg and can cause severe instant burns when in contact with skin. 50 deg feels hot, yet without the dangers of burning. When required, the output temperature of the tempering valve can be adjusted between 40-50 deg.

Fresh Air Upgrade for My 2024 Impreza
Installed this in my 2024 Subaru Impreza, and it fit perfectly—no issues. The air smells noticeably cleaner now, and it took less than 10 minutes to swap out. The carbon and HEPA filtration does a great job clearing out odors, dust, and pollen—definitely an upgrade over the factory filter. The build feels sturdier than the OEM version, though it does have slightly fewer pleats. Might mean it needs replacing a bit sooner, but for the price and performance, I’m fine with that tradeoff. If you’re looking for a quick, affordable way to improve your cabin air, this one’s a solid pick.

Well built, good fit.
I like it so well, I just bought two more to keep on the shelf for when the price doubles. Seems better built than oem, but I don't know how you can judge the filtration; seems good though.

Works Fine, Fits Fine
Size: (Pack of 1)
Seem to work and fit just fine and should be better than a cheap paper filter. They cost more but I change the oil on the 5's and the filter on the 10's so it evens out. Not going more than 10K on the filter. If you are only going to use the filter for 5K miles I would stick with the Toyota factory filter. I use the K&N filters on a 2017 Toyota Sienna and a 2018 Toyota Highlander. Both are V6
