79.99 new on the mothership. I have a smaller Winix filter…Anyone have this Shark that is happy with it? And are the filters expensive?
I think you’re mistaken…$79.99 on mothersship says refurbished and sold + shipped by WOOT!!
On Amazon the filters are $44 for one and $71 for two of them.
Amazon also has the air purifier itself new (in black) for about $250 and they’ve also got a refurbished black one for about $150. I didn’t grab a link for the $150 refurbished one.
I’ve been shopping for a large unit for a while now and ended up getting a awesome deal on a Dayette that handles a 4000sq feet. I only paid $139 with a $70 off coupon on Prime day sale. It’s coming Monday and I’m hoping I like it as much as the Happi air purifier that just crapped out last week. It really spoiled me but my wallet is too tight to spend $400! I’m also looking forward to the Alexa feature. Fingers crossed it blows me away!
