Things To Consider Before Buying

You need to know the square footage of the area that you are looking to purify, first and foremost, so that you can buy the proper size unit in order to suit your needs. The next thing that you are going to have to decide is the amount of money that you are willing to spend on a unit as the more you spend on a unit, generally the more high tech of a system you will get.

Dust and Allergen Capture Rate:

One of the common things you will find on air purifier’s is a percentile number as to the amount of dust and allergens that the unit is capable of capturing. This number will likely be quite high in a good quality unit and you should look for something in the high 90 percent range in order to get something of a good quality. When you are looking at units it may be a good idea to compare ones of a similar price range in order to see which ones are the best at collecting dust and allergens as this will result in better, cleaner air in your home. It is always a good idea to read through the product description in order to see the kinds of materials that it can filter so that you don’t have to worry about things like mould spores, bacteria etc. as a good quality air filter should be able to remove dust, allergens as well as multiple other particles from your air.

Unit Size:

One thing that can cause issues for some people is the actual size of the air purifier. Especially if you are buying something that isn’t the most eye appealing design, it is certainly nice if the unit isn’t huge and doesn’t take up a large portion of your living area. Generally the manufacturer will list the dimensions of the unit directly in the product description, but if you are having a hard time finding the dimensions of the unit, don’t be afraid to contact the manufacturer or leave a note on a forum somewhere as a good company, or a nice person is very likely to get back to you pretty quickly. It is important to note that if you are looking for an air purifier to purify air in a very large room, the unit is likely to be larger than a purifier that is only meant to be able to purify air in a small room.

Filters:

One of the main things that you need to know about air purifying units is that they come containing different filters. In the description of the product that you are considering purchasing you will generally find a model number for the filter of the product. Depending on the unit that you buy, the replacement time for the filter may vary. It is always a good idea to look up the filter that the unit uses and check the price of it compared to the other units that you are thinking of purchasing as some are certainly more expensive than others and even though the unit itself may be cheap, you might end up paying a lot replacing filters down the road so this is definitely an important factor to consider. One other thing that you may find when it comes to filters is that they are made out of charcoal. Depending on your home situation this may be something that you may want to look out for as a charcoal filter helps to reduce odors in your home and helps with things like odors from cooking, pets and even things like smoking.

Speed:

One thing that you may want to look for, especially if you want to be able to move the unit around your home is some kind of a variable speed ability on the unit. Being able to increase or decrease the speed of a unit can make it so that you can put it in areas of lower or higher square footage as you need and be able to reduce hydro costs by decreasing the speed of the unit in areas that you don’t need it. Always remember if you are doubtful about company claims, you can always get in touch with people who have previously bought the unit and get their feedback rather than asking the company itself.

Unit Noise:

Another thing that kind of goes along with the speed of the unit is the amount of noise that it makes. This can be a difficult one to figure out as the company may over exaggerate how quiet the unit is in the description of their product so that it sounds as good as possible to the consumer. Sometimes the manufacturer will include the dba of a unit though and this is definitely something that you should be on the lookout for. The lower the dba, the quieter the unit will be. Keep in mind that a normal conversation is at an average of around 65 dba, so you will probably want to find a unit that is a fair bit quieter than that in order to find something that won’t be a bother. If you go shopping in person for an air purifier you may find that the store has models on the floor and you may even be able to ask a sales rep to be able to test out the unit in order to see firsthand exactly how loud it is; remember it never hurts to ask questions. Keep in mind that most sales reps are generally getting a commission on each product that they sell you, so you should try not to feel too pressured into buying a particular unit. Instead it is a good idea to take your time and think it over and make the decision that is the best for yourself.

CADR Rating:

This is probably one of the most important numbers to look at if you are looking to have clean air in your house. This number means clean air delivery rate, the number is a figure that will tell you the cubic feet per minute of air that the unit is capable of removing particles from. The higher that this rating is, the more purified air your unit is creating. Not all air purifying units are of the same quality which is why this number will range from unit to unit and this is definitely something that you should take a look at if you want to have the maximum amount of clean air.

Hydro:

If you are looking to be as environmentally friendly as possible, one of the things that you may want to look at is the amount of power that the purifier uses. You will notice things like watts, voltage, amps as well as Hz when you are searching around for the right unit for your household. If you are looking to get an air purifier that you can simply plug into your wall then you are going to want to search for something that is 120 volts as this is the power of a regular household wall plug. You can contact the manufacturer for hydro usage specs if you don’t want to go through the hassle of calculating them yourself, or if the information isn’t available in the product’s description then this may be something that you should be doing anyways.

Energy Star Rating:

If a unit has an energy star rating then you will be able to clearly see the projected amount of cost for the unit for the year. An energy star rating on a product means that it uses anywhere from 10-50 percent less energy than a standard appliance. Having this rating on a product means that it is good for the environment compared to similar products on the market. The actual energy star program is a government program that helps people to be able to identify products that use less emissions and it is used on all kinds of different appliances, in factory equipment, office equipment and even electronics. An energy star rating is certainly something to be on the lookout for if you are looking to be green and if you are looking to save money over time thanks to a reduced hydro bill.

Fancy Features:

If you are looking to get yourself something in the higher price range then there are plenty of cool features that you should be on the lookout for. You will find things like air purifiers that have technology which allows them to be able to self-adjust to the current air quality in order to run harder or run at a lighter speed as needed. Other things that you may also find are air purifiers that actually will show you how clean your air is at any given time. This is a good way to be able to tell how well your air purifier is working as well as to be able to see how much progress it has made over time. The more expensive the unit that you buy, generally you will find a more sophisticated display on the unit to let you know these kinds of details. If you are really looking to get something fancy, there are units that can connect to Wi-Fi or a 3G or 4G network and provide you with real time data as to how your air quality is doing. This advanced technology is quite useful as it will allow you to see the progress of your air quality over time and may even help you to narrow down some of the things that are causing your household to have bad air.

Settings:

One thing that you may want to look for when you are looking at air purifiers is that they have manual as well as an automatic setting built into their design. If you get a cheaper air purifier it may just have a manual mode which is something to keep in mind. Depending on the unit that you buy you may even see modes that help to eliminate particular items. Things like a virus mode, a bacteria mode as well as something like a dust mode are all things that you should expect to see if you look at a bunch of the units that are available. One thing that you may want to look for if you want to keep your costs down over time is a product that has an auto shut off feature built into its design. Generally this setting allows the unit to shut down if the filter is not working properly in order to prevent poor air from ever coming out of the unit. These systems will often warn you ahead of time so that you know that you will be needing a new filter before it is too late.

To Conclude:

Hopefully this article has taught you some things that you should be on the lookout for as far as air purifiers go. There are plenty of options available on the market and without having any knowledge about what all the specifications of the units are, you would probably end up buying yourself something that isn’t of the best quality. Always remember to make sure that you check into the company warranty as well as the return policy on any unit that you are thinking of purchasing so that you can have some peace of mind. Good luck in your search for the best air purifier and hope that you find one that works for both your square footage and that lasts you for a very long time.
