Do any of you own himalayan salt lamps?

Tweet

I spend 8 to 10 hours every day in front of my computer screen...on top of that the tv is usually always running in the next room, my husband smokes like a chimeny, we have cats and a dog....so with all of these allergens in the air i know my house is FULL of positive ions.... I know there are certain plants you can put in your house that give off negative ions but i have never been good at keeping any plants alive for very long so i was looking for an alternative to that... Ionic breeze air ionizers are just too expensive....I did find a small thing that you can plug into a wall outlet that is suppose to emit a huge amount of negative ions but it has no aesthetic value at all and it was over 50 dollars.. So I came across these himalayan salt lamps and they are supposed to emit negative ions as well.... I think they are beautiful and wouldnt mind getting one just for that reason but i was wondering if any of you have one of these and if so do you notice any difference in the quality of the air in the area where you have it or any difference in your mood, health, alergies etc?
