Considerations For picking the best air purifiers for odors

  • Filter type and quality

When dealing with smells, the air purifier you purchase must have a hepa filter and an activated carbon filter. Which are the two distinct features that are required in an efficient filter. The hepa filter removes about 99.97% of allergens in the atmosphere, while the carbon/ charcoal filter is solely responsible for dealing with the odors or smells.  Most top air cleaners also possess a secondary pre filter in a 3 or 4-stage air filtration process.

  • Size:

The quality of an air purifier depends mostly on how large an area it can cover efficiently. Depending on the size of your home or room you purchasing it for, you should purchase an equivalently sized device.

  • CADR Rating and AHAM Clarification:

The best types of air purifiers always have a high CADR (clean air delivery rate) rating, which is the cubic feet per meter which the device covers. The AHAM (Association of Home Appliance Manufacturers) goes on to measure how goof CADR ratings are, and it follows a 2/3 rule that states that the smoke CADR must be greater than or equal to 2/3 of the room area in square feet.

  • Energy star certification:

Energy star only certifies products with a maximum efficient power saving system that helps save electricity cost. This comes in handy, why spend further high sum on electric bills when you can use products that would perform effectively. And keep the bills low.

The best way to deal with the smells in the home is by identifying their sources and attacking it there.

Different types of bad smells in the house

The different kinds of bad smells have been streamlined into a few classes accordingly:

  •  Dirty-skin like smell:

This occurs as a result of the presence of pets or a high amount of rodents in the home, mostly has a need-a-bath smell and signals that you could have an animal or insect problem. Most rodents get stuck in neglected parts in the home like the attic, wall or storeroom.

  • Stuffy and mold like smells:

This smells like those high level of humidity that leads to the sweaty moist odor in the atmosphere. An object that portrays it the most is a dirty sock. These smells are very toxic to those in the home especially those with asthma and allergies whose symptoms become worse with exposure to mold.

Some of these are most dangerous and for all their deadliness, do not possess any detection substances. A typical example is carbon monoxide which doesn’t smell like anything but is easily breathed in by the body and could do a whole lot of damages in minutes, leading to anxiousness and even death. Electrical appliances mostly release them in the home like space heaters, gas and wood stove, fireplace, car engines.

If you can, you should have a carbon monoxide detector at home as well as a smoke detector; they should be placed in strategic places around the home to ensure that gas doesn’t become trapped in one place.

Once the sensor goes off, you should move outside immediately to breathe in fresh air and call 911 immediately if there are flu-like symptoms on exhibition. You should also open all the doors and windows if you can to vent the gas from your home.

  • Rotten eggs:

This is one of the most recognizable stenches at home, and the two most common sources are the natural gas leak and sewer leakages. Natural gas is very odorless, but for safety reasons, the gas is mixed with mercaptan which gives it the rotten egg odor.

If there is a gas leak, then the obvious step is the call 911 and abstain from lighting up any fire. Rotten egg smell is also as a result of sewer gas that emanates when there is low water level in the u-shaped trap where water usually blocks the sewer gas from leaking back into the home.

This type of air pollution is very obvious when present in the home, and could be as a result of many things, all of which are bad for your health, and you signify you should leave your home immediately and call 911 for help.

How to detect smells in the house

Though the several potential sources of odors in the home have been discussed, identifying the specific source of the odor may be quite complicated, because most originate from the combination of several sources working together, some, however, could be noticed easily due to their signature repugnant smell (e.g., rotten flesh of decaying animals). If you are finding it difficult to detect smells in the home, then we advise you to call in a professional.

Do air purifiers remove smells

This one of the most sort out questions when it comes to air purifiers, and the simple answer is a YES, it removes smells but it depends on the type of product you use. There are so many manufacturers out there that would claim their device eliminates odors, but when put to the test, it turns out not to be true; most of these devices are cheap. It is crucial you get a good and proven air purifier to help with your odor in the home.

The primary element in an air purifier that gets rid of odors in the atmosphere is the activated carbon filter. Without this feature, your device wouldn’t be effective in removing smells.

The activated carbon filter contains microscopic spores that absorb particles that carry odors, and these particles are attracted after air is sucked into the device and passed through the carbon filter. The more significant the amount of carbon in the filter, the more effective the device would be at absorbing odors.

How to get rid of cat odor in the air : Without best air purifier for cat litter smell

Cats are very adorable, but their odor could be very discomforting to deal with, from urine to dander and unbathed skin. This is why we have put together a few steps to eradicating the odors they release into the atmosphere without using the best air purifier for cat litter smell

  • Clean their urines:

If your pet is fond of urinating in places outside their litter box, then that’s extra work for you, and we recommend you clean it immediately, as the longer it stays on a fabric material, the more difficult it becomes to remove the smell. If it is on a carpet or furniture, placing an absorbent paper over the spot would also serve as a faster way to reduce odor, although it wouldn’t absorb all the urine, it would certainly reduce your workload in cleaning what is left.

  •  Apply an enzymatic cleaner:

The job of enzymatic cleaners are to break down smells that are released by pets such as urine odors, eradicating it completely. This also ensures that your cat doesn’t end up soiling the spot again. This product can be purchased at any pet store and should be used alone, as when mixed with other cleaning agents, it always ends up diluted and less effective.

  • Clean with extra wet VAC:

This releases clean water into the floor material (carpet or rug), and then suck back dirty water into the tank. As this dirty water comes off, it takes along with itself the urine smell particles off the rug, therefore leaving it with less odor than it originally had.

We advise you don’t use wet steam cleaners because intense heat could actually cause the odors to fuse in more with the material and become more of a mainstay, i.e., making it more difficult to remove.

  •  Apply air freshener:

Baking soda is a powerful odor eliminating agent, and it can be used in dealing with smells from the cat’s urine while making the atmosphere smell sweeter. Combining a teaspoon each of crushed dried herbs (rosemary, lavender, etc.), ground cloves, baking soda, and cinnamon would do, then you sprinkle on the area, leave it for a while (about 20-30mins) and then vacuum it.

  • Use vinegar:

White vinegar precisely removes smells of animals. It just need to be applied to the spot, rubbed vigorously and left to evaporate taking the urine smell with it.

If after all these procedures, the air odor is not eradicated completely, as it still takes a while for the odor to be fully removed. Then you should employ an air purifier.
