Yes. Because of the size (not the weight), shipping might be a surprise. PM to me an address or at least a ZIP code, and I will be able to get an estimate of the shipping in a couple of days. Thanks.
Update. You have a message with shipping information to a randomly chosen Las Vegas ZIP Code. Check your conversations.
Update 2. This person joined the site made one post inquiring about the air filters and has never returned to the website for any reason nor replied to messages. Takes a lot of patience to deal with this stuff.
Yes they are still available.
Box: 3.5 pounds. 8x12x18". Decide how you want it shipped and go to that website for a shipping estimate. Payment by PayPal.
Contact me if you are actually serious.
