Oxygensolve's Columbus Day Sale offers up to 50% off selected oxygen concentrators and health and beauty products, with an extra 18% off on top. This is the brand's best current deal and the one to use for most shoppers on the sale items you want.
On a budget or buying new items: If you are shopping for new arrivals under three items, the Up to 25% Off New Arrivals deal is available on those products. Compare this to any Columbus Day price on the same item (the Columbus Day sale covers selected items only, not everything). Whichever shows the lower total is the right one for you.
When buying three or more items: The 20% Off When You Buy 3 Items sale applies when you add three or more products to your cart. This is a fixed 20% off your order and needs no code. On a basket of three items priced at $100, $75 and $80, for example, you would save $51 (20% off $255), bringing the total to $204. Compare this to what you would pay with the Columbus Day Sale if your items are among the selected products, or the New Arrivals deal if your items qualify instead. Take whichever leaves the lowest total.
On selected sale items with multiple qualifying offers: If your items appear in both the Columbus Day Sale and another active deal, work out the final price under each to see which saves you more. On a $100 item reduced to $60 in the Columbus Day Sale (40% off), the extra 18% off brings it to $49.20, saving you $50.80. Compare that to 25% or 20% off the original $100 price, or to any combination if terms allow stacking (the offer descriptions do not state whether discounts combine, so calculate each offer alone). All promotions apply at checkout automatically, and all are available on the website only.
In the 12 months to October 2026, our team tested three Oxygensolve offers at checkout. The biggest sale or deal in that period was up to 50% off (December 2025), matching the current Columbus Day offer, so this is a strong deal worth using now rather than waiting for something larger.
