Austin Air - Pet Machine

You don't buy a purifier for removing hair, that's not the function. And your purifier is not for pet odors as its for any odor. 1. Be honest on the square footage. If you leave the door of the bedroom open you just turned the right sized purifier into the wrong sized purifier. Either the door is always closed and you need a 150 sq ft unit or you need one for the bedroom + the hallway + the other 2 bedrooms, so you really want a whole house 2000 sq ft model. Same logic applies to the living space as unless its closed off, you want one for the entire area. 2. If item 1 is frustrating, you can alleviate this by just buy two 1000 sq ft units for your 2000 sq ft house and spread them equidistant. Or one 2000 sq ft unit. 3. The big BIFL brand is Ausin Air as it has a 5 year warranty, 5 year filter and also comes with carbon filter for smells. Find the unit(s) to cover your area's size.

So here's the thing - Austin sells a purifier with 15lbs. of carbon. They estimate that will last 5 years of "moderate use". This means that the amount of carbon needed to remove VOC/odor from the air part-time is 3lbs. per year by Austin's estimation. Many people think that isn't enough. Airpura has 26lbs. and Allerair also has more than 20. IQAir has 5-6lbs. and expects that to last 2 years - again of moderate use not continuous. So if you have a moderate smell and run the purifier a couple hours a day... you might get the 5 years from an Austin. But without 15lbs. of carbon, you don't get the airflow-over-volume that you would need, that's the other problem. Adsorption requires slow air flow over a large volume of carbon, the opposite of what budget air purifiers provide.

Austin Air - it’s a tank and made in USA. No fancy controls . Heavy metal frame big fan. Filters last 5 years. Some of their filters can filter chemicals.

I ended up getting an expensive Austin air purifier appropriate for medical use because all the cheaper brands i looked at intentionally or accidentally produce ozone, which is not healthy to breathe.

Austin Air air and other similar air cleaners that are made of metal, not plastic, is an indication that these companies are designed for the most discerning customer. Plastic and glues off-gas VOCs so they are counter productive to removing VOCs. The Austin Air and other serious air cleaners have multiple pounds of activated carbon in their filter, not several ounces that last for a few weeks if the VOC off-gas from the plastic filter housing didn't use up half of it while it sat on a boat from China. The Austin Air has a HEPA filter integrated into the filter cartridge that also includes the activated carbon. Austin Air, E.L. Foust and a few others are next level air cleaners. Did you ever wonder why that HEPA air cleaner didn't take out those fumes or odors? It's because it had a tiny pre-filter impregnated with a few ounces of activated carbon that got used up in a couple weeks.
