Air Vent Filters Buying Guide

Air Purifiers for Allergies: Are They Effective?

As We Know, Home Air Purifiers Are Mainly Purchased by Allergy, Asthma, or Other Respiratory Ailments Sufferers.

Another Question that Arises Therefore Is: Do Air Purifiers Work and Are They Able to Drastically Reduce the Presence of Bacteria, Pollen, Mold, Fine Dust, and Other Particles?

There Can Be No Dry Answer to This Question. There Is No Doubt that The Purifiers Manage to Sanitize the Indoor Air, but There Is No Scientific Proof of Their Effectiveness in Improving the Pathologies Mentioned Above.

Furthermore, as We Will See Later, Some Models Can Even Contribute to Domestic Pollution if Not Used Correctly.

So, Together with The Purchase and Use of A Purifier, It Is Always Good to Follow Some Common Sense Behaviors. In other words, following a few simple rules could increase the effectiveness of the cleaner.

Among these: do not smoke in the house; do not allow animals to enter the rooms or allow them to climb on beds and sofas; air the house often; limit the use of carpets; limit the use of heating (in this case, it might be a good idea to buy a wi-fi thermostat for intelligent air conditioning management ).

How to Choose the Best Air Purifier for Your Home

To choose the best air purifier for your needs and your home, you need to do some research. As we have said, there are numerous options on the market, with prices also very distant from each other.

One of the first differentiating factors of air purifiers is certainly the purification system. There are different types. Let’s see them in detail.


Indeed, the most common purification system on the market is based on filters. The latter are of different types, and it is possible to have more than one within the same cleaner.

The greater the number of filters, the better the product’s performance in terms of air cleaning will be. The results of purification by filtration are, on average, very high.

However, this type of air purifier requires more frequent maintenance (filter replacement) and consumes more energy (the air must pass through several layers). Below, the most common filters.

  • Carbon filter: thanks to the porous structure, activated carbon can capture the molecules responsible for bad odors, transforming gases into liquids. The activated carbon filter system can be used only, or together with other types of filters. In fact, by its nature, it can retain only the largest particles and is therefore not suitable for all kinds of dust present in the air.
  • Anti-Dust: This Filter Allows You to Capture Larger Dust Particles, to Avoid Annoying Traffic Jams in The Main Filter.
  • Hepa Filter: Hepa Means High-Efficiency Particulate Air. The Presence of This Type of Filter Is Essential. in Fact, These Are Capable of Retaining Particles up To 0.3 Microns in Diameter. Pollen, Mites, and Molds Will Then Be Trapped. This Type of Filter Is Certainly the Most Effective on The Market. Therefore, the Best Air Purifiers with Filtration Will Be Equipped with This Technology.
  • Photo-Catalyst Filter: This Filter Uses Titanium Dioxide and Ultraviolet Rays to Kill Organic Agents (bacteria and Viruses).

Thermodynamic Sterilization

With This System, the Impurities Present in The Air Are Destroyed by Heat. The air, by Convention, Is Sucked Into the Ceramic Core of The Product, Where It Is Heated to A Temperature of 200 Degrees.

In This Way, It Is the Heat Itself that Destroys the Harmful Particles. Once “cleaned,” the Air Is Put Back Into Circulation, Obviously After Being Cooled.

Unlike the Purification System with Filters, with Thermodynamic Sterilization, There Is No Need to Replace the Filters. Furthermore, the Energy Consumption Is Lower And, Overall, These Purifiers Are Quieter.

Ionizer and Ozone Generator

Ionizer appliances use so-called electronic polarization to trap particles in the air. These products can produce negative ions that are bound to the latter, charging them electrically.

At this point, an internal filter with an opposite charge will attract them by trapping them. As a rule, this technology is combined with another filter system. Overall, it is very effective.

Some models produce a small amount of ozone to remove odors and destroy particles and allergens.

However, it is good to pay attention to this feature. The level of ozone in the air must never exceed a certain threshold (50 parts per billion is the limit of sanitary appliances, even if this is still under discussion).

Too high levels of ozone in the air could create complications, as the molecule can bind easily to react with other substances, such as household air fresheners.

The result is the production of new irritants such as formaldehyde or acrolein. So, it is good to have the right caution when buying an air purifier with an ozone generator, and it is advisable to buy one that detects the concentration of this gas in the air, to regulate its production accordingly.

Ultraviolet Irradiation

Ultraviolet irradiation air purifiers are professional cleaners that use UV-c rays to sterilize the air. This is pushed with a fan towards UV lamps, which burn the particles.

This type of system has excellent germicidal potential and is particularly suitable for molds and organic substances. However, these air purifiers are not popular in the home.

Other Purification Technologies

On the market, it is possible to find some alternative solutions, which we are sure will manage to carve out a good slice of the market.

Nature smart air purifier natural plant review among these, we point out nature, the natural air purifier that uses the plant phytoremediation process, and the photocatalytic filter for air purification. If you want more information, you can read our full nature review.


In addition to the main cleaning function, the best air purifiers offer several other features. For example, some models can be used as dehumidifiers (but not as humidifiers ). It is a handy option in humid environments and subjects to mold formation.

In this way, it is, therefore, possible to eliminate “upstream” some of the impurities that can be found in the air. Not only that, but some air purifiers are also fans (see Dyson).

Also, most cleaners on the market allow programming and setting of custom timers. Another noteworthy function is undoubtedly the night mode,

Smart Functionality

Some of the best air purifiers are equipped with smart features. In other words, they are really intelligent home products, connected to an app.

Through this, it is possible to monitor the air quality in the real-time, program the appliance and also manage it remotely (switch it on, switch it off, change the mode, etc.)


Before purchasing an air purifier, it is necessary to consider the size of the environment where the appliance will be positioned.

Each purifier manages to cover more or less cubic meters with its action. Usually, the larger the product size, the better the flow rate.

It is, therefore, possible to switch from appliances capable of sanitizing tiny rooms (a room, car) and positioned on a shelf, up to professional purifiers capable of cleaning the air of an environment of more than 100 square meters.

Therefore, it is necessary to consider this factor to avoid the purchase of air purifiers not suitable for the specific environment in which they will operate.

Cadr and Air Flow

In the technical specifications of an air purifier, it is possible to find the wording cadr. What is it about? This acronym stands for a clean air delivery rate and indicates the air volume that is purified in one minute.

Sometimes, unfortunately, the unit of measurement is expressed in cubic feet, so it may be difficult to understand the capacity of the product if you are not entirely familiar with anglo-Saxon measurements.

For ease, just remember that one foot equals about 30 cm. for many models, however, it is also possible to find the price in cubic meters.

Also, the cadr is not a generic number but is calculated based on the type of particle or fine dust.

These have a different size, and the air purifier will use different times to sanitize each type. For example, molds have different sizes than pollen or dust mites.

Of course, cadr cannot be taken as a stand-alone factor, but must necessarily be related to the coverage of the purifier itself. Conversely, it is possible to make a calculation that allows you to understand, given the size of the environment, how much the cadr of the product should amount.

Just convert the square meters into square feet (1 square meter corresponds to about 10 square feet) and divide the result by a coefficient of 1.55. the number obtained in this way corresponds to the minimum cadr value for those particular dimensions.

Air Flux

Another measure is that of the airflow, which simply indicates how much air per minute is filtered by the purifier. This specification, too, must be related to the flow rate of the appliance, understand the time required to sanitize a specific environment.

How Much an Air Purifier Consumes

Generally, these products have reduced consumption, but it is still advisable to check the energy absorption before completing the purchase.

These products are often kept in operation for several hours, and too high absorption could have unpleasant consequences on the bill.

Of course, if, in addition to the filters, the product offers more than one air purification technology (UV rays, ionizer), the consumption will be higher.

However, it is most of the models on the market do not exceed 50 w. however, we recommend moving on models that do not exceed a maximum absorption of 100 w.

Maintenance Required

In general, the maintenance of air purifiers is simple and requires no special effort. Regular replacement of the filters is required, which generally should be carried out every three months.

Of course, the timing also depends on the intensity of use of the appliance and the time of year (in spring, due to pollen, it is advisable to change it more often).

Fortunately, many cleaners have a reminder function, which alerts you when the time for replacement has come.
