I’m debating if I should get an air bath or not. I don’t want a whirlpool as I’m concerned about upkeep. However, I would like some agitation and my understanding is the air tubs/baths blow out warm air that keep the water warmer longer. Is this true? Can anyone who has an air bath or has experienced one provide any feedback, which tub they have, and if they would recommend it? Level of maintenance? I’m looking at the Produits Neptune Elysee or Revelation air bath tub. Any one have those tubs? Thanks
