The Airfree P1000 is just one of the many filterless air purifiers that have continued to become popular among consumers seeking to breathe cleaner air, and get rid of dust mites, mold spores, bacteria viruses and pollen from their environment. It\u2019s also pretty unique, as it uses filterness technology to get rid of these airborne microorganisms, with a level of efficiency that\u2019s not any less than what you\u2019d expect from an air purifier that\u2019s got a true HEPA filter. While the Airfree P1000 air purifier still doesn\u2019t pack enough punch to be called the Best Air Purifier around, it\u2019s still a great option for anyone looking for the Best Filterless Air Purifier under $250, so if this sounds like your budget, then make sure you get to the end of this review.\r\n\r\nWhy We Like It - Airfree P1000\r\nThe Airfree P1000 is a reliable, well designed and filterless air purifier that destroys mould, bacteria and any other airborne contaminants to improve the air quality in your living space. The unit relies on Exclusive patented Thermodynamic TSS technology that uses heat to kill microorganisms in the air, guaranteeing completely silent & emission free operation.\r\n\r\nPower\/Speed\r\nAs you\u2019d expect from an Airfree Air Purifier, the technology used here is that of a Patented Thermodynamic TSS, where high intensity heat is used to destroy any microorganisms in the air. This process is completely silent, and is sure to destroy any dust mites bacteria or viruses that might happen to be present in the air. The same Patented Thermodynamic TSS technology is also applied by the P3000 Airfree Air Purifier, and with both units being around the same size and weight, you\u2019ll easily be able to move them around as much as you\u2019d need to.\r\nEfficiency\r\nOne of the things that a lot of people tend to seriously consider when purchasing a new electrical appliance for their home is the amount of electricity that is going to be consumed. With the Airfree P1000 filterless portable air purifier though, this shouldn\u2019t be something to worry about. The unit guarantees low energy consumption, as it doesn\u2019t have any fans that need to be powered. It\u2019s also pretty efficient in terms of room coverage, as it is well suitable for a room size of up to 450 square feet.\r\nVersatility\r\nBeing a silent air purifier, you\u2019re guaranteed of no disruptions if you choose to use the Airfree P1000 air purifier at night as you sleep. Just like the Airfree Iris 3000, the unit also features a blue night light to help you create a comfortable environment, but there\u2019s no timer you\u2019ll be able to use to schedule its functioning, as all you need to do to switch it on is to plug it into an electricity socket.\r\nDurability\r\nThe good thing about getting any Air Purifier Airfree is that there\u2019s literally no additional costs for you to incur once you purchase the unit. It is completely maintenance free since there\u2019s nothing you\u2019ll need to replace, and with a guarantee of completely silent air cleaning, an adjustable night light and a generous 2 year warranty, it\u2019s pretty much one of the best air purifiers there is.\r\nValue\r\nInstead of using a UV light filter type to provide clean air like the Airfree T800 does, the Airfree P1000 relies on an air sterilizer technology that does not emit any harmful ozone air, and neither does it emit any ions. It\u2019s process is completely harmless to the environment, and is also both small and lightweight for easy portability.\r\nAirfree P1000 Wrap Up\r\nHeadquartered in the United States and manufactured in Europe, you can rest assured that Airfree products are of exceptional build quality. They\u2019re sure to provide long lasting service, and are very energy efficient compared to other types of air purifiers.
