EcoQuest International

Call it what you want, the Living Air Classic or the EcoQuest XL-15, it's still the same unit that has been the workhorse in EcoQuest's line of air purifiers for almost 15 years. It should be discontinued soon because of more advanced models from EcoQuest like the Fresh Air, but you can still get a good deal on one from eBay.
