My house looks great but it stinks

My house looks great but it stinks

My house stinks, or at least I think it does. I feel like if I think so, then guests must agree even more. We live in a 2 bedroom apartment. We have two kids and a dog. I clean every day, and I have taught my children to help clean too. The house looks and feels great, but it stinks.
I’m not sure how to fix this. There is daily floor sweeping and mopping, dishes are cleaned after every meal, laundry gets washed every 2 days. Every Sunday, we do a deep clean where everything gets cleaned and vacuumed – fridge, pantry, cupboards, sofa, showcase, etc.
Despite all this, I still feel like it stinks. It’s stuffy and just off-smelling, even after leaving the windows open all day and night.
Are there certain products I should use, is there something I’m missing? I just want my house to smell as nice as it looks.
 
EKAM’s Home Fragrance Tips:
If the house stinks despite regular cleaning and airing, then we suggest calling a plumber to check the bathroom and kitchen plumbing. There is likely a plumbing issue that is causing a backflush and stinking up the whole house.
You should also check your house for leaking pipes and damp walls, which can also make it smell musty and stale.
The other possible cause is that your dog is shedding too much hair, causing your house to smell like wet clothes all the time.
Checkout EKAM Air Freshener Plug-ins in your bathroom to overcome any unpleasant odors emanating from the toilet. Easy to use- you just have to plug it into the power socket and use it as long as you need (advisable to not use it continuously for over 8 hours) or when guests are visiting.
Using EKAM’s Aroma Diffusers with essential & aroma oils when guests are visiting can easily fragrance up to 250 sq. ft. which will make your house smell rich and as luxurious as a premium hotel lobby or palatial bungalow.
EKAM provides no questions asked refund or replacement within 10 days of purchase. Tour diffusers also come with one-year warranty.
