THE 1-2-3 GUARANTEE 1.  30 Day Satisfaction Guarantee: Some of our competitors have an unconditional 100% guarantee, but only if you return the filters in the unopened package.  Others only give you 10 days and you must return the filter in the original packaging.   Not us!  If you are not completely happy, send them back opened, unopened, or any way you want, (within 30 days) and we'll give you a full refund of the purchased price, with the limitation stated in our business policy. 2.  30 Day Low Price Guarantee: If you find a website advertising a lower price within 30 days of check-out, simply send us a copy of the ad or email us the web address and we will meet their price, and send you a free 1/2 lbs. tub of ClenAir Odor Neutralizer.  This offer cannot be used with any other special or discount offer.   3.  No Hidden Costs Guarantee:   The price you see on our website is the price you'll see on your charge card.  We do not add tax (except Florida residents), handling charges, re-stocking charges, or anything else.
