A weird smell in a house can come from numerous sources, including appliances, furniture, carpets, fabrics or issues like mold or mildew. Occasionally, odors may be caused by sewer gas, natural gas leaks or animals that have died between walls, in attics or under decks.
HVAC Issues: A dirty air filter or mold in the HVAC system can circulate bad smells throughout your home. Plumbing Problems: A clogged drain or sewer issue can lead to foul odors, particularly in kitchens and bathrooms. Stagnant Air: If your house is sealed tight, stagnant air can accumulate odors.
There are many sources of bad smells in and around the home including spoiled food, mold, volatile organic chemicals, leaky or backed-up pipes and drains, and pet odors. Mixing some household cleaners such as bleach and ammonia or acid can produce toxic fumes. Some toxic fumes such as carbon monoxide are odorless.
Scientists have classified odors into 10 basic categories: fragrant, woody/resinous, minty/peppermint, sweet, chemical, popcorn, lemon, fruity (non-citrus), pungent and decayed.
Some of the hardest and worst smells to get rid of are pet odours, mold, and cigarette smells.
A bowl of vinegar can start absorbing odors almost immediately and is typically adequate for up to 24 hours. When left out in a room, the acetic acid in vinegar neutralizes alkaline odors, such as those from smoke, cooking, or pet accidents, by binding with the odor molecules and neutralizing them.
Toxic black mold growth has a more potent and identifiable smell, like the smell of decay, wet soil, or rot. Visually, it may be greenish-black, grayish-black, slimy, or more furry than other forms of mold or mildew.
Apparently there is something called “Occupant Odor.” These odors come from the detergents you use, cooking smells, cleaning supplies, and room fresheners. These scents then occupy spaces like curtains, carpets, cushions and pillows. Combined together, the meshing of these scents creates your distinct home smell.
Freon is generally odorless in small quantities, making it difficult to detect leaks based on smell alone. However, when a leak occurs, a faint, sweetish odor may be noticeable. Some people describe this smell as similar to acetone, nail polish remover, or even chloroform.

Radon gas has no colour, smell or taste and is completely imperceptible to humans, even in high concentrations. Radon occurs naturally in the rocks and soil beneath us, but there is no way of knowing how much is escaping from the ground and entering a building.
Odor sensors have been extensively used to detect gas leakage and in fields such as healthcare, mobility, and spatial environment control, in which the detection of low-concentration biogas and odor is crucial [3].
Actions to take: Locate the source of moisture or water intrusion that is causing the dampness and musty smell. Look for leaks around pipes, windows or the roof. Check for condensation on walls or pipes.
The smell of sewer gas is often described as a noxious, rotten-egg-like odor. Its sulfuric, foul smell will permeate your entire home if left unaddressed, leading to major health issues down the line. Small amounts of sewer gas usually won't cause any immediate danger—but large amounts certainly will.

Some of the best odor eliminators are coffee grounds, tea, vinegar, oats, and baking soda. Leaving a bowl of any of these odor absorbers out in a room that's due for a little freshening up will help clear out the less-than-pleasant smells from the air.
The olfactory system is at the roof of the nasal cavity at the cribriform plate - a perforated portion of the ethmoid bone separating the frontal lobe of the cerebrum from the nasal cavity. Odorant molecules within the nasal passages first encounter receptors on the primary cilia of olfactory sensory neurons.
Pungent: It is a sharp and bad smell. These scents make a person feel when they smell it. Examples include blue cheese, cigar smoke, fecal matter (e.g., manure), sweat, and sometimes, smells of onion and garlic.
