Filters And Performance

As the name suggested, Lasko 42 Wind Curve comes with an air ionizing feature that can provide you with natural fresh air while reducing indoor heat. The built-in ionizer will disperse millions of negative ions into the air that bond with positive ion particles e.g. dust, hair, dust mite, mold, pollen, smoke, and bacteria. The bonded ion particles will become heavier and fall to the ground effectively removing them from the air. Unlike a HEPA filter that will trap the fallen pollutants, you do have to perform house cleaning like vacuum or mopping the floor to prevent the irritants from building up or stir back up into the air. The good news is there is no filter to maintain or replacing needed ever.

Noise And Energy Usage

Let's briefly go through this part as it is very subjective depending on the individual. Lasko 42 Wind Curve Tower fan ionizer is very quiet at the lowest speed with or without turning the ionizer on. At any other speed, there is a distinctive spinning motor fan noise spinning similar to most tower fans out there. If you cannot sleep or work with a background white noise, you will need to place the tower fan air purifier further or kept it at the lowest speed.

Power consumption is also a mixed bag. If you used it as an air purifier/ ionizer, it will be very energy-efficient (less than 50 W) even if you leave it running 24x7. If you treat it primarily as a fan + air purifier, it will consume quite a fair bit of energy that could cost you depending on the state you're in.

Depends on which angle you're looking at it. Lasko 42 Wind Curve tower fan ionizer T42950 is very affordable for an air purifier with a price of around 70 dollars after discount. On the other hand, it can also be categorized as costly for a fan that adds an ionizing feature. We're on the affordable side as there are not many options for an air purifier fan that comes with such a heritage. Best of all, there is no recurring filter replacement cost to bear. What you see is what you'll get.
Last we checked, Lasko's official website does not have an e-commerce store. The only way to get your hands on Lasko 42 Wind Curve T42950 is through your local retailers like Best Buy, Walmart, Target, and of course on Amazon. Amazon comes with the best price, bundled deals, free shipping (with prime), and 30 days return policy if you are not happy with the purchase. There's added prime protection plan as well if you need the extra peace of mind.
