国外流行国内静默 静电集尘空净水土不服?

2017-08-23 09:13:23   中国经济网

空气净化器领域的技术分为两大流派,一个是人们通常见到的HEPA过滤式,另一个是静电集尘式。在国内,采用HEPA滤网式技术的产品几乎占据百分之百的市场份额。在国外,却并非如此一边倒,静电集尘式产品的市场份额差不多有三成。事实上,静电集尘式产品具有诸多优点,无耗材、低能耗、几乎静音,但是似乎不受中国消费者青睐,陷入水土不服的困境。

静电产品优点多接受度低

据了解,静电集尘技术来源于美国,主要是利用正负电荷相吸的原理,通过高压形成强电场,产生大量电子和离子,与空气的颗粒物(例如PM2.5)碰撞并附着,然后被净化器中的集尘板吸附,从而去除颗粒物、净化空气。整个过程中,净化器不需要电机、不需要滤网,集尘板只需要经常擦拭干净,保养得当,就可以长期使用。

家用静电集尘式产品在设计上通常具有清理便捷的特点,无需专业人员帮助,几分钟就可以完成一次擦拭清理过程。相对地,HEPA过滤式产品需要定期更换滤网,二次使用成本高;有电机和风扇, CADR值(净化效率)越大噪声越大;耗电量高。

相对HEPA过滤式产品,静电集尘式产品的优势明显,在市场上的售价也不高。一款适用于20~40平方米的静电集尘式产品,售价通常在2000~3000元之间,与当下主流品牌同样CADR值的净化器产品的价格并没有差异。

在国外,静电集尘式产品也比较受欢迎。在日本市场,某品牌静电集尘产品在近5年内销量超过400万台。在美国,线上空气净化器销售排名第一的也是一款静电集尘式产品。据空气净化器企业贝昂科技董事长兼总经理冉宏宇透露,静电集尘产品在美国市场占有率达到20%~30%。

然而,这样一种看起来具有很明显技术优势的产品,在我国空净市场上的占有率还不到5%。《2017上半年家电网购市场分析报告》显示,2017上半年,空气净化器线上市场静电集尘式产品的市场占有率仅有0.1%,几乎可以忽略不计。

如此少的市场占有率,确实令人吃惊。大多数中国消费者只知道HEPA过滤式产品,不知道静电集尘式产品,而且国内生产销售此类产品的企业也很少。据冉宏宇透露,中国市场上该类产品一年的出货量仅在20万套左右。
