Smart Air (Distributed by SmarterHEPA) - SA600

I have a 250 sq-ft room and no complaints with my units CADR at Speed 4 & 5.. I'm using a SmartAir SA600. It only uses 14 Watts on speed 4 and the CADR is still sufficient. I measured mine as follows. * **Speed 4** → 320 m³/h @ 14 Watts (not noisy) * **Speed 5** → 508 m³/h @ 58 Watts (noisy at this speed) I chose the SA600 because its the only purifier that I could buy locally which has real HEPA H13 filters. I was thinking to get the Xiaomi Pro 4 purifier, as it appears to have nearly equal CADR for less money, but they are actually using a less dense "high-efficiency" filter to get more airflow. The problem is after it loses its electrostatic charge; its capture rate for ultra-fine particles will drop quickly. The SA600 uses a more dense H13 filter, so it will have superior capture rates for the entire lifespan of the filters. This is why I believe the SA600 requires two H13 filters, because they are using more dense HEPA filters. (which require two to create equivalent airflow of other units which only use one less dense filter)

Any hepa air purifier will deal with all mould spores. The higher the CADR the better. The biggest problem is nearly all companies only tell you the CADR of the highest setting. Which most people don’t tend to use. I’d advise a smart art purifier - the sa600. Really high CADR and nice and quiet. Long term…you’re correct. Your floorboards are going to be covered in mold growth and really need to be replaced. Any you able to reach the floorboards, are they under Lino etc?

SA600 is a great choice by smart air

Yay! Same here. Been using it for more than a year now. Practical and perfect

Agreed 💯, a lot cheaper units are better. Self made CR box, smart air SA600 & mini blast & blast, Air Fanta,clean air kits -expensive, northbox, nukit,

Smartair sa600 is my unit. No nonsense filter.

Yes, we have Smart Air SA600

We've just purchased a Smart Air SA600 based on recommendations in a FB Still Coviding group. Pleased with it so far and the lower level settings are very quiet. Worth also looking on cleanairstars.com for info on best filters for your needs

I second the Smart Blast Mini! I have one and it works great. It has a very high CADR (clean air delivery rate) so in a small place with just one living room and 2 bedrooms, all that may be required is one. Unfortunately they raised the price recently due to tariffs, so it's over $700 now, and OP couldn't afford two. I'd go with a Smart Blast Mini for the LR and an SA600 (same brand) for the bedroom. OP, see this [link](https://smartairfilters.com/en/shop/?=header) for the purifiers.

Looks interesting, but not as widely available as a Xiaomi. The Xiaomi 4 Pro and the Smartair SA-600 appear to have the most directly comparible CADR ratings (500 vs 508 claimed) Prices are from Lazada Xiaomi store or WEDO air, an official supplier of SmartAir in Thailand [SmartAir SA-600 Review](https://housefresh.com/smart-air-sa600-review/) Cost: 10900 [Xiaomi 4 Pro](https://housefresh.com/xiaomi-4-pro-review/) Cost 7010 SmartAir Replacement Filter cost (Requires 2X HEPA plus 2X Carbon) 990+890= 1880 Xiaomi Replacement Filter cost (1 HEPA, with built in Carbon filter) 1349 The SA-600 is fully manual, basically a box fan with a filter. The Xiaomi has an air quality meter and an auto mode.

The SA600 are really good and they've recently improved them with more control over the airflow.

[This one in particular](https://smartairfilters.com/uk/en/product/sa600-air-purifier-5-speed-version/) would be my recommendation as a balance between size and affordability. We have one of the larger models as well as a couple of these, and I think these are more versatile.

Smart Air (SmarterHEPA in the US) is our main filters with an AustinAir in the bedroom. AustinAir is one of the only with a large amount of carbon or carbon fabric in them for VOCs and odors.
