You are not alone. I can smell people's body odor and it's (ironically) especially bad when a smoker passes by me. Even if it's been a while since their last smoke. Like everyone already pretty much suggested, I have a variety of air fresheners everywhere. Candles, sprays, oils, incences...in my car alone I have about 5 or 6. (In every vent and under the seats.)
Other tips: Clean your house even if it's already clean. Furniture, fabrics, and even walls and woods absorb odors. Use a safe deodorizing agent, like vinegar. It's good for getting rid of odors and is cheap and all natural. I sometimes use an upholstry cleaner like Woolite, and carpet deodorizer too.
Adeline is on to something too. Baking soda absorbs odors in the air which is why it's used in refridgerators.
Yeh, I've done most of that. I'm fortunate in that I have hard floors and leather furniture. The only thing I haven't done is walls as they're vaulted and I'm getting up there in years and getting up there on a ladder has never been my forte

but I have painted frames, doors, etc.. anything I can reach on a stool or short step ladder. I think the smells are more about trash, pup pads, even bedding and pillows. I used to only wash spreads and pillows once a month and now its every week. I laid on the couch the other day and the smell of the
throw pillow bothered me and it was washed a month ago. I don't think I ever washed those before but just
threw them out and got new ones to change up looks. Also, we are rural and the smells that come in even with windows closed sometimes nearly gags me and I used to enjoy having the windows open. Oh, well, its an adjustment and I'm sure, in time, I will make it.
Thank you everyone for your great input. Its helped to know I'm not alone in this and I've written down some really good tips. I'm know I'm going to be shopping for the most fragrant candles I can find this weekend... and some of those decorative gel type things to set next to me.
